Need a little help here; I've just reinstalled this, and all of a sudden, the game won't run. Every time I try to start up the game through the launcher, I'm given the standard Vista "[program] has stopped working" pop-up. Attempting to run the game using the witcher.exe file also does not work, even when run as an administrator. Anyone have any clue why it's doing this?

I forget which standard info to post, so for now, here's what appears in the pop-up.

*EDIT* Forgot to mention; yes, I have tried reinstalling the June 2010 DirectX release.

Huh, very odd; seems the game doesn't like me running in 1600x900 fullscreen. Well, I can live with that; problem solved, I suppose.
