Burgzergarcade Why am i getting an error after re-importing?

I have been following Burgzergarcade's tutorials and i had made a back up of my project to test something. And when I went to re-import it, everything seemed to work but when I play it I get an error.

This is the error:

NullReferenceException: Object reference not set to an instance of an object GameSettings.LoadCharacterData () (at Assets/Scripts/GameSettings.cs:48) GameMaster.LoadCharacter () (at Assets/Scripts/GameMaster.cs:61) GameMaster.Start () (at Assets/Scripts/GameMaster.cs:47)

Here is my GameSettings.cs:

 using UnityEngine;
 using System.Collections;
 using System;
 
 public class GameSettings : MonoBehaviour {
     public const string PLAYER_SPAWN_POINT = "Player Spawn Point";        //this is the name of the gameObject that the player will spawn at at the start of the level
     
     void Awake(){
         DontDestroyOnLoad(this);                                        //allows script to surive from scene to scene
     }
     
     public void SaveCharacterData(){
         GameObject pc = GameObject.Find("pc");
         
         PlayerCharacter pcClass = pc.GetComponent<PlayerCharacter>();
         
         //PlayerPrefs.DeleteAll();        //use when adding or editing Vitals, Attributes, or Skills *Note: uncomment (Set - Mods when this is done)
         
         PlayerPrefs.SetString("Player Name", pcClass.Name);
         
         for(int cnt = 0 ; cnt < Enum.GetValues(typeof(AttributeName)).Length; cnt++){
             PlayerPrefs.SetInt(((AttributeName)cnt).ToString() + " - Base Value", pcClass.GetPrimaryAttribute(cnt).BaseValue);
             PlayerPrefs.SetInt(((AttributeName)cnt).ToString() + " - Exp To Level", pcClass.GetPrimaryAttribute(cnt).ExpToLevel);
         }
         for(int cnt = 0 ; cnt < Enum.GetValues(typeof(VitalName)).Length; cnt++){
             PlayerPrefs.SetInt(((VitalName)cnt).ToString() + " - Base Value", pcClass.GetVital(cnt).BaseValue);
             PlayerPrefs.SetInt(((VitalName)cnt).ToString() + " - Exp To Level", pcClass.GetVital(cnt).ExpToLevel);
             PlayerPrefs.SetInt(((VitalName)cnt).ToString() + " - Cur Value", pcClass.GetVital(cnt).CurValue);
         
 //            PlayerPrefs.SetString(((VitalName)cnt).ToString() + " - Mods", pcClass.GetVital(cnt).GetModifyingAttributeString());
             
         }
         for(int cnt = 0 ; cnt < Enum.GetValues(typeof(SkillName)).Length; cnt++){
             PlayerPrefs.SetInt(((SkillName)cnt).ToString() + " - Base Value", pcClass.GetSkill(cnt).BaseValue);
             PlayerPrefs.SetInt(((SkillName)cnt).ToString() + " - Exp To Level", pcClass.GetSkill(cnt).ExpToLevel);
         
 //            PlayerPrefs.SetString(((SkillName)cnt).ToString() + " - Mods", pcClass.GetSkill(cnt).GetModifyingAttributeString());
                         
         }
     
     }
         
     public void LoadCharacterData(){
         GameObject pc = GameObject.Find("pc");
         
         PlayerCharacter pcClass = pc.GetComponent<PlayerCharacter>();
         
         pcClass.Name = PlayerPrefs.GetString("Player Name", "Name Me");
         
         for(int cnt = 0 ; cnt < Enum.GetValues(typeof(AttributeName)).Length; cnt++){
             pcClass.GetPrimaryAttribute(cnt).BaseValue = PlayerPrefs.GetInt(((AttributeName)cnt).ToString() + " - Base Value", 0);
             pcClass.GetPrimaryAttribute(cnt).ExpToLevel    = PlayerPrefs.GetInt(((AttributeName)cnt).ToString() + " - Exp To Level", Attribute.STARTING_EXP_COST);
         }    
         
         for(int cnt = 0 ; cnt < Enum.GetValues(typeof(VitalName)).Length; cnt++){
             pcClass.GetVital(cnt).BaseValue = PlayerPrefs.GetInt(((VitalName)cnt).ToString() + " - Base Value", 0);
             pcClass.GetVital(cnt).ExpToLevel = PlayerPrefs.GetInt(((VitalName)cnt).ToString() + " - Exp To Level", 0);
             
             //make sure you call this so that the AdjustedBaseValue will be updated before you try to call to get the curValue
             pcClass.GetVital(cnt).Update();
             
             //get the stored value for the curValue foreach vital
             pcClass.GetVital(cnt).CurValue = PlayerPrefs.GetInt(((VitalName)cnt).ToString() + " - Cur Value", 1);
         }
         
         for(int cnt = 0 ; cnt < Enum.GetValues(typeof(SkillName)).Length; cnt++){
             pcClass.GetSkill(cnt).BaseValue = PlayerPrefs.GetInt(((SkillName)cnt).ToString() + " - Base Value", 0);
             pcClass.GetSkill(cnt).ExpToLevel = PlayerPrefs.GetInt(((SkillName)cnt).ToString() + " - Exp To Level", 0);
                 
         }
         //output the curValue for each of the vitals
         for(int cnt = 0; cnt < Enum.GetValues(typeof(SkillName)).Length; cnt++){
 //            Debug.Log(((SkillName)cnt).ToString() + ": " + pcClass.GetSkill(cnt).BaseValue + " - " + pcClass.GetSkill(cnt).ExpToLevel);
         }    
     }    
 }

And here is my GameMaster.cs :

 using UnityEngine;
 using System.Collections;
 
 public class GameMaster : MonoBehaviour {
     public GameObject playerCharacter;
     public GameObject gameSettings;
     public Camera mainCamera;
         
     public float zOffset;
     public float yOffset;    
     public float xRotOffset;
     
     private GameObject _pc;
     private PlayerCharacter _pcScript;
     
     public Vector3 _playerSpawnPointPos;            //this is the place where i want my player to spawn.
     
     // Use this for initialization
     void Start () {
 //        _playerSpawnPointPos = new Vector3(466, 145, 720);    // the default positition for our player spawn point (used to be 1008, 66, 212)
         
         GameObject go = GameObject.Find(GameSettings.PLAYER_SPAWN_POINT);
         
         if(go == null){
             Debug.LogWarning("Can not find Player Spawn Point");    
             
             go = new GameObject(GameSettings.PLAYER_SPAWN_POINT);
             Debug.Log("Created Player Spawn Point");    
             
             go.transform.position = _playerSpawnPointPos;
             Debug.Log("Moved Player Spawn Point");    
 
         }    
         
         _pc = Instantiate(playerCharacter, go.transform.position, Quaternion.identity)as GameObject;
         _pc.name = "pc";
         
         _pcScript =_pc.GetComponent<PlayerCharacter>();
         
         zOffset = -2.5f;
         yOffset = 2.5f;
         xRotOffset = 22.5f;
         
         mainCamera.transform.position = new Vector3(_pc.transform.position.x, _pc.transform.position.y + yOffset, _pc.transform.position.z + zOffset);
         mainCamera.transform.Rotate(xRotOffset, 0, 0);
     
         LoadCharacter();
     }
     
     public void LoadCharacter(){
         GameObject gs = GameObject.Find("__GameSettings");
         
         if(gs = null){
             GameObject gs1 = Instantiate(gameSettings, Vector3.zero, Quaternion.identity) as GameObject;
             gs1.name = "__GameSettings";
             
         }
         GameSettings gsScript = GameObject.Find("__GameSettings").GetComponent<GameSettings>();
             
         //load the character data
         gsScript.LoadCharacterData();    
     }
 }

If you see any errors in my script or if you need more info let me know.

Thank You.
