FileFront Forums - Start up problems!

Hello.

Both the Outcast and the Acadamy.

Now, the thing is, I can start my Jedi knights game anylonger.
I have my pc formatet in a pc shop cause of some virus ect ect.

Now I can install Jedi knight (from Outcast demo to Acadamy) BUT I cant start them.
I get at "warning" which reads:
