RPC Call failed

Ok, so I get this error whenever I try to load a scene via RPC,

And here's my script containing the code that causes this problem somehow:

 using UnityEngine;
 using System.Collections;
 
 
 
 public class Network_Menu : MonoBehaviour {
 
 
     public string IP = "127.0.0.1";
     public int Port = 25000;
     
 
     
     
     void OnGUI()
     {
      if(Network.peerType == NetworkPeerType.Disconnected)
        
         {
             
             GUI.Label(new Rect(100,75,300,25),"You're currently not connected or hosting a game.");
             
         if(GUI.Button(new Rect(100,100,350,25),"Connect to server (Local only for the moment)."))
             {
             
             Network.Connect(IP,Port);
                 
                 
             }
             
             if(GUI.Button(new Rect(100,130,100,25),"Intialize Server"))
             {
             
             Network.InitializeServer(4,Port);
                 
                 
             }
             
             
         }
         
         else {
             if(Network.peerType == NetworkPeerType.Client)
             {
         
                 
                 
                 GUI.Label(new Rect(100,100,300,25), "You're connected as a client");
                 
                 if(GUI.Button(new Rect(100,125,130,25), "Disconnect")){
                 
                     
                     Network.Disconnect(250);
                     
                 }
                 
                 if(GUI.Button(new Rect(100,150,110,25), "Enter Game")){
                 
                     
                    networkView.RPC("ConnectToScene",RPCMode.All);
                    networkView.RPC ("PrintText",RPCMode.All);

                 GUI.Label(new Rect(100,125,178,25), "Players that are connected: " + Network.connections.Length);
                 
                 
                 if(GUI.Button(new Rect(100,150,200,25), "Shut down server and go back")){

             }
             
         }
         
         
         
         
         
     }
     
       [RPC]    
       void PrintText(string text)
         
     {
         
         print("You are connected!");
     }

         void ConnectToScene()
         {
         
             Application.LoadLevel(2);
               
         
            }
         
         }
