I was playing a Single Player tournament, and when I was done and was going to exit Demigod, I got an bluescreen. Never happened before, so I was surprised. But I got another surprise after I've restarted my computer. When I started Demigod all of my data was gone, my single player profile, my finished tournaments, my SP achivements and favor points, and the options was returned to default.
Are there some files that has useful information which I should paste here?
