First, I read the posts about the hotfix and it doesn't apply to (it said that when I tried to run it). When I start the game I get a black screen and then a message pops up saying that the game asked runtime to close it in an unexpected way. This started two days ago and I have had the game installed for three weeks now (it had been fully updated the whole time). No other message shows up. When I reinstall the game it will run just fine but if I try to update it the game crashes just like I described. I also don't get any messages about mini dump files so I don't know if that applies to me.
My setup:
Vista Business 32
Pentium D 840
3 GB memory
Creative Audigy 2 ZS sound card - latest drivers installed
e-GeForce 8800 GTS SSC - with the 175 drivers installed
