Emerald-Knight

I just bought KOTOR 2 and installed it. When I begin the game, it runs perfectly. I create my character and begin a new game. It shows the intro clip of the Ebon Hawk and then the screen goes black while the music continues to play. It doesn't show any error message or anything, it just remains on a black screen until I ctrl, alt, delete to get out. My comp meets all of the specs and I have tried restarting the computer and then playing again, but it doesn't work. If anyone has any suggestions, they would be greatly appreciated.
