I have a similar problem, when I first got the game, it was fine. I could load missions and stuff but one day, it just kept crashing saying 'DCS etc has stopped responding' and going back to the game menu.
The actual game .exe has broken somewhere as when I try to load a mission, wether it's training, multiplayer or a single mission, it loads all the way in to about 75% including dropping out to windows and loading back in but then it freezes or crashes. Once that happens the menu loads back up again as if nothing happened.
This only happened a few weeks after playing the game, not long after I defragged my hardrive so I assumed that caused some kind of corruption. Today I reinstalled the game hoping to play but only to find that I still have this problem.
I'm running Vista 32bit
Geforce 8800Gt with latest drivers
4Gb RAM
500Gb Hardrive
Any help would be appreciated, it can't be my antivirus or anything, I didn't have any problems with it before and it doesn't affect any other games (Symantec antivirus).
Just looked in the crash file, opened it with notepad and I see this:

If I need to add anything else, let me know. Really want to get back into playing this!
