Object Reference Not Set To An Instance Of An Object!

Hey! I've been trying to get a simple UFPS player to work over a Photon Network. I came across this error:-

NullReferenceException: Object reference not set to an instance of an object NetworkManager.SpawnMyPlayer () (at Assets/NetworkManager.cs:47) NetworkManager.OnJoinedRoom () (at Assets/NetworkManager.cs:35) UnityEngine.GameObject:SendMessage(String, Object, SendMessageOptions) NetworkingPeer:SendMonoMessage(PhotonNetworkingMessage, Object[]) (at Assets/_Imported/Photon Unity Networking/Plugins/PhotonNetwork/NetworkingPeer.cs:1769) NetworkingPeer:OnEvent(EventData) (at Assets/_Imported/Photon Unity Networking/Plugins/PhotonNetwork/NetworkingPeer.cs:1612) ExitGames.Client.Photon.PeerBase:DeserializeMessageAndCallback(Byte[]) ExitGames.Client.Photon.EnetPeer:DispatchIncomingCommands() ExitGames.Client.Photon.PhotonPeer:DispatchIncomingCommands() PhotonHandler:Update() (at Assets/_Imported/Photon Unity Networking/Plugins/PhotonNetwork/PhotonHandler.cs:76)

In my script I referenced a component on my UFPS Player GO "Vp_FPController" Here is the script :-

 using UnityEngine;
 using System.Collections;
 
 public class NetworkManager : MonoBehaviour {
     
     SpawnSpot[] spawnSpots;
 
     // Use this for initialization
     void Start () {
         spawnSpots = GameObject.FindObjectsOfType<SpawnSpot>();
         Connect ();
     }
 
     void Connect() {
         PhotonNetwork.ConnectUsingSettings( "FPS Game 0.00004" );
     }
      
     void OnGUI() {
         GUILayout.Label( PhotonNetwork.connectionStateDetailed.ToString() );
     }
 
     void OnJoinedLobby() {
         Debug.Log ("OnJoinedLobby");
         PhotonNetwork.JoinRandomRoom();
     }
 
     void OnPhotonRandomJoinFailed() {
         Debug.Log ("OnPhotonRandomJoinFailed");
         PhotonNetwork.CreateRoom( null );
     }
 
     void OnJoinedRoom() {
         Debug.Log ("OnJoinedRoom");
 
         SpawnMyPlayer();
     }
 
     void SpawnMyPlayer() {
         if(spawnSpots == null) {
             Debug.LogError ("NO SPAWN POINTS FOUND!!!");
             return;
         }
 
         SpawnSpot mySpawnSpot = spawnSpots[ Random.Range (0, spawnSpots.Length) ];
         GameObject myPlayerGO = (GameObject)PhotonNetwork.Instantiate ("SimplePlayer", mySpawnSpot.transform.position, mySpawnSpot.transform.rotation, 0);
 
         ((MonoBehaviour)myPlayerGO.GetComponent("Vp_FPController")).enabled = true;
         ((MonoBehaviour)myPlayerGO.GetComponent("Vp_FPinput")).enabled = true;
     }
 }

I'm not sure why the GameObject isn't being referenced as I am in the script clearly asking to enable it (The script is supposed to enable the component once the player spawns into the game.)

I have disabled the component, could this be why? I've tryed it with the component activated but that doesn't do what I want it to do...

If you guys need to know anything else please be sure to ask and I'll provide.
