DiRT 2 executable has stopped working

To make a long story short, DiRT 2 executable has stopped working, say I load a route and the game crashes, this happens mostly after 2 races.
I now have scoured all forums, drivers etc reinstalled etc.
It has helped everything nothing and I find it an impudence Codemasters to release something, let alone having something patching, the patch 1.1 by the way also not helped.

To all who complain about Live Mircosoft, you can create an account and you would need OFFLINE not ONLINE to AKTIVIEREN.Einfach startup disconnect from the Internet and create an account offline, ready.

The game itself is top, graphics, steering wheel control, everything was great if it were not the crashes. :(
