Exakt das war wohl das Problem. Nach Freigabe kann ich ingame in Winlive einloggen. Fragt sich nur, ob die Freigabe des Kerberos Protokolls andere Probleme mit sich bringen könnte
I had a very similar problem to this with Dawn of War 2 Beta.
I couldnt log into Games for Windows - Live without my Firewall being switched off. After login, i could switch the Firewall back on.
Being unsatisfied with this work-around and finding no help on the forums, i spent several hours trying to find the Problem.
I found that my Firewall (sunbelt) blocked "Kerberos Protocol" traffic by default.
By permitting Kerberos Protocol traffic, i can now sign onto Live without turning my Firewall off.
I found this Protocol blocked in a predefined Network security tab of my Firewall. You should be able to allow Kerberos traffic with Sygate.
Hopefully this solves your problem.
