FSX Gamespy Problem, please help?

hello, my flight simulator X multiplayer is not working properly. Every time I try to join a pass worded session, i click it, and that 'connecting...' screen comes up, as usual... but then, the screen just disappears and i'm back in the 'free flight' lobby. Non-passworded sessions work normally though, but i don't usually go into those. Please help, this is getting really annoying.

Password sessions are private. They are usually hosted by a website that yu have to join to get the password. Look in the additional details section when joining. You can only access sessions with no passwords, because they are open.

no that's not it, i know the password to the session... but whatever, i fixed it, SP2 was causing the problem, and uninstalling it did the trick :D http://answers.yahoo.com/question/accuse_write?qid=20081016170952AAVD6ZG&kid=DqNxJDHJFG0mV05l7jhk&s=comm&date=2008-10-29+16%3A41%3A54&.crumb=
