I'm using a laptop. Also tried running as admin and on several packs of compatibility mode, including win7.Do you have more than one monitor connected to the computer?
Also, Run as administrator has worked for some save issues.
That's the only thing I can think of right now. I checked my notes for problems people have reported for this game, but I don't find anything about this exact issue.
I don't know if it'll help, but it gave me this error log.
EDIT: Also, thanks a lot for the speedy responses, even if it ends up being something we can't solve.
