I have a Windows XP and an Nvidia 9600GT with the newest drivers. I also have the Steam version of the game.
So my issue is that I installed the game after years of having last played it. And I started it normally without problems, got to the level selection too. But as soon as I load a level, the game crashes with no error message.
I reformated my PC since the last time I played it, but I don't think that should matter?
