Yes, I figured it was a corrupt install, so I reinstalled... five times so far. This last time I turned off everything before install, all windows security, avast, firewall, even firefox, everything. Even so, this last is even more corrupted: when I try to switch to windows with Alt+Tab or Windows button, or turn the game off, it goes to black screen, and I have to turn the computer off manually. My question is: WHAT could be still interfering with the install? And only the WA? I'm new to W7, I bought it only a week ago...
I see you had the same problem, did a simple reinstall fix it or what else did you do?
So, sixth reinstall, back to square one: black screen, manual reset. I think I'll go back to Morrowind for a while...
