Well, that is very strange because it is still working for me. Perhaps this will help you:
1. Is DirectX updated? If DirectX is updated it WILL NOT work!
2. If you are on Vista, make sure both processes are identical to eachother. What I mean by this is: If you are running the Injector as admin, make sure the game is running as admin too. If both are not run identical (either both on admin or both regular) then it won't work.
Also: When does the game crash? This will help me help you. See, I've done some testing and if you press the delete key too early (before it gets to your character screen) it crashes. It also crashes when loading the map (when it gives the tip and the blue bar loading). The time I press the hotkey is when my character screen is up.
