I have updated the XNA, the .NET and my graphic card’s driver, but I still cannot manage to play the game.

I can access the menu, log in, but when i attend to start the tutorial or any kind of game, it crashes.

Here is the ErrorLog :

System.NullReferenceException: Object reference not set to an instance of an object.
  at PlainSight.UILayer.UnloadTextures()
  at PlainSight.GameplayScreen.UnloadContent(Boolean hardExit)
  at BeatEngine.ScreenSystem.ScreenManager.UnloadContent()
  at Microsoft.Xna.Framework.DrawableGameComponent.Dispose(Boolean disposing)
  at Microsoft.Xna.Framework.GameComponent.Dispose()
  at Microsoft.Xna.Framework.Game.Dispose(Boolean disposing)
  at Microsoft.Xna.Framework.Game.Dispose()
  at PlainSight.Program.Main(String[] args)

Note that the error was always the same, even before i did the updates.

I am running on XP SP3, and my graphic card is a GeFORCE 8800 GTS 512.

Thank you.

Shameless self-bump for still being unable to play for several weeks by now.

I had to format and reinstall all my system, of course it hasn’t changed a thing.

can you check to see if you have any windows updates?
