Dirt 1 and 2 problems

So I just bought the Codemasters Racing pack on stream which includes Dirt 1&2, Grid, Toca 3, and Fuel and after installing the Dirt games and Grid I am unable to play them. The games allways close back to the desktop with a message "Dirt Executable has failed" or something like that. After searching around on the net for a little bit I think the problem is because im running Windows 7 32 bit. Can someone please give me some advise on how to get these games running?

Have you tried the Steam forums? It may be a steam specific issue.C_Rule

Not yet, Ill go ask over there real quick. Thanks :)

Not sure about Dirt 1 but Dirt 2 and Grid use Games for Windows Live, have you tried installing latest version?
