Compiler errors need help with. Please

Hi Everybody,

I recently started a Unity3D project just to experiment with the game engine. When I tried to compile my project into a executable for the PC it came up with three compiler errors. I don't have a clue what these errors are referring to and how to fix them. I welcome anybodies help to fix this problem for me. Thank you.

Here's my compiler errors:

ApplicationException: Unable to find a suitable compiler UnityEditor.Scripting.ScriptCompilers.CreateCompilerInstance (MonoIsland island) (at:C:/BuildAgent/work/14194e8ce88cdf47/Editor/Mono/Scripting/ScriptCompilers.cs:87)

Failed to create compiler instance

KeyNotFoundException: The given key was not present in the dictionary. System.Collections.Generic.Dictionary'2[System.String,UnityEditor.VisualStudioIntegration.ScriptingLanguage].get_Item (System.String key)

Here's my script for my project that I'm trying to get to work just in case it is something to do with this:

 var inputString2 : String;
 private var saveString2 : String;
 
 function OnGUI()
 {
      inputString2 = GUI.TextArea(Rect(600, 250, Screen.width-1200, Screen.height-570), inputString2);
      if(GUI.Button(Rect(430, 285, Screen.width-1200, Screen.height-570), "Submit Name"))
      {
           saveString2 = inputString2;
      }
      if(GUI.Button(Rect(600, 285, Screen.width-1200, Screen.height-570), "Display Name"))
      {
           inputString2 = saveString2;
      }
      if(GUI.Button(Rect(770, 285, Screen.width-1200, Screen.height-570), "Play Game"))
      {
           Debug.Log(saveString2);
      }
      if(GUI.Button(Rect(600, 320, Screen.width-1200, Screen.height-570), "Exit Game"))
      {
           Application.LoadLevel(0);
      }
 }
