I don't know if this pertains to your issue and this suggestion does not come from experience as I learned it from paying attention to the help given here at the Glitches Forum. Many have suggested to install games on Windows 7 anywhere but the Program Files. Like the Desktop, My Documents or creating a games folder. The reason, as I have read, is that Windows 7 doesn't always recognize saves in games and their location in Program Files like previous Windows OS's.
