I've got a similar problem. CSS crash while I'm starting it.
1.are you running dual monitors?
2.What drivers are you running for your graphics?
3.do your nvidia network access manager(called something like that) installed?
4.Have you tried running your game with your sound disabled?(at device manager)
5.Have you tried running a game at a lower dx level? (In launch properties put one of these in -dxlevel 80 , -dxlevel 81, -dxlevel 90 )
6.Is UAC Running
7.Is there a Firewall running
2. Most recent - I installed Windows 7 today
3. I do not have NVIDIA network access manager
5. Yes and it sounds it works.
6. Yes, but it doesn't make anything.
7. Exception done.
Another strange thing to this, is that I can run the game by double clicking the CSS shortcut on the desktop, created by steam, but not in the steam Window. Once I try tu run the shortcut under administrator privileges, it crashs and I can't use the shortcut anymore. Disabling UAC do absolutly nothing I've try myself this solution.
Can you help me please?
