After a few hours I closed my game. When restarting I got the wonderful F1 2011.exe has stopped working. 3 forums and a day later I have so far got it back. I deleted my profile in Games For Windows Live. GFWL is found in Steam folder/steamapps/common/f1 2011/GFWL. When you have the GFWL Marketplace open (and logged in) click on settings, profile management, clear. Then I downloaded the Beta 285.27 Nvidia drivers. I did not uninstall the older drivers. I can not say which one fixed the problem but it does now work as before with no other issues in game. Thanks to all and hope this helps someone else.
