Hi!
I just reactivated my account. Sadly I'm not able to play since the game won't start. Everything works fine until the loading screen (the little picture with LOADING...) shows up because after that nothing happens. I'm totally clueless why this happens. I checked the file integrity with the updater and tried to shut down the firewall.
Are there any other options? I'd really hate to reinstall the whole game.

If this helps, I'm using XP however the game worked just fine before...
Thanks in advance.
Ps: I used the search but couldn't really find anything that helped. Maybe I overlooked something.
