Today,fallout 3 starting crashing shortly after the first "please stand by" loading screen appears on start up (fallout 3 has stopped working). I have the steam copy, and i have tried, the busethreadedAI trick, dragging the DLL file into fallout 3, re-installing, etc and to no avail. Can somebody help me because im about to give up on this game. Im on a windows 7 system.
