I'm still puzzled. As I say, the software has worked perfectly well since I got this PC about a year ago. I was working on the DB this morning, and it was fine. Now I've tried to use it again and it either won't display, or crashes when I tried compatability mode.
That chess db might be useful, but I need something to work with my database(s).
Try uninstalling and reinstalling again but make sure that you reboot the computer in between. (Possibly even better though, do a registry clean-up with CCleaner, and then reboot, between unistalling and reinstalling). That can sometimes shift a 'sticky' reistry item that's causing a problem.
