First I updated "Microsoft Games for Windows - LIVE" ingame after starting F1 2010. The Install seems successfull, but after restarting F1 2010 "Microsoft Games for Windows - LIVE" wants to update again. So I tried to update "Microsoft Games for Windows - LIVE" manually over microsoft.com. After that, F1 2010 crashes at every start, too. So I uninstalled the newest "Microsoft Games for Windows - LIVE" - Version and installed the one on the F1 2010 DVD. So I can play the game, but only offline (because the game wants to update "Microsoft Games for Windows - LIVE" to play online). I hate such things. I bought F1, not "Microsoft Games for Windows - LIVE". I hope they will fix that joke soon.
