Right after posting this tread the game started working again, but only fore a few days.... Now it dosen't work at all. I have to uninstall and intall the game on steam if I want to play. So now I have checked out some stuff on DirectX Diagnostic Tool. Name: 256MB ATI Radeon X1300PRO, Manufacturer: ATI Techologies Inc., Chip Type: Radeon X1300 Series (0x7183)
So i think i have got a ATI videocard, but can't find out where to update it, if I need to. And i'm not how to find out if I have got an "indeo" codec on the game disc. If it is the code you need to type in a box when you're installing a game (AH14F-254DF-SFDGF-23FG5, something like that) i have got it.
Or else pleace tell me how to find out
