Hey everybody!
About 2 weeks ago i bought the game Caesar 3. I played for several days, but at some point (approx. a week ago) it didn't work anymore. I just opened it as usual and it was just loading all the time. It doesn't open no matter how long i wait. So, does anybody know anything about that? I must mention i use Windows 8. Please help! I love that game :( Thank you in advance, you guys!

Copy your save files somewhere safe, uninstall the game and reinstall from the begining.
Since you managed to start the game and play for days, I believe the problem is not within the game.

Just a thought Diana, but have you installed any security programmes, or has there been a security update since you began playing Caesar 3?

I'd have a look via Control Panel - System and Security - Restore at what system updates have occurred (this is the route for Win 7, but there must be a similar route for Win 8), to see if might be worth restoring your computer to an earlier time when your game worked.
