UnitySerializer Only Saving one Game Problem

I know that UnitySerializer has its own forum but there is no one on it that uses it any more and you cant get help. I am hoping some one here my have used this product and hit this same issue and fixed it.

When playing the game you can click the save button and save the games just fine and they load up just fine but when I close the game build and reopen it, it only shows one game save.

Here is the save script I am using:

 using UnityEngine;
 using System.Collections;
 
 public class GrassSaveGame : MonoBehaviour 
 {
     public GUISkin Box;
     public GUISkin Box2;
     public string gameName = "Your Game";
     private string box;
     private bool paused;
     
     //Awake is called when the script instance is being loaded.
     void Awake ()
         
     {
         LevelSerializer.MaxGames = 5;
     }
     
     // Update is called once per frame
     void Update ()
     {
         if(Input.GetKeyUp(KeyCode.P))
         { 
                paused = !paused;
  
         if(paused == true)
         {
             Time.timeScale = 0.0f;
             //if(pausedGUI) pausedGUI.enabled = true;
         } 
             else 
         {
             Time.timeScale = 1.0f;
           //  if(pausedGUI) pausedGUI.enabled = false;
         }
          
         }
 
         
     }
     
      void  OnGUI ()
     {
         if (paused)
         {
          GUILayout.BeginArea(new Rect(400,200, 300, 400));
         GUILayout.BeginVertical(); 
         GUILayout.FlexibleSpace();
             
         
             GUI.skin = Box;
             if(GUI.Button(new Rect(55,0,200,55),box))
                 {
                     LevelSerializer.SaveGame(gameName);
                 }
             
             GUILayout.Space(5);
                 foreach(var sg in LevelSerializer.SavedGames[LevelSerializer.PlayerName]) 
                         { 
                            if(GUILayout.Button(sg.Caption)) 
                               { 
                                 
                                            LevelSerializer.LoadNow(sg.Data);
                                           Time.timeScale = 1;
                     
                               } 
                      } 
             GUILayout.EndVertical();
             GUILayout.FlexibleSpace();
             GUILayout.EndArea();
         }
  
      }
             
 }
