Its a known problem in Vista, nothing else. (you can google it)
They sent out an update to fix it but it still happens once in a while
I sometimes get the same thing on CoH
I rarely get a problem where the game used to crash instantly when it was started, before it even could pop up. I used to get a driver not responding error in LOTR:BFME several times in a row (3 to be exact, when I finally exited the game it popped up 3 times), but the game kept chugging along. As said, maybe it's a Vista thing.
