Ok, so I like MANY others, had a million problems w/ trying to get, and stay connected, I reconfigured my router, and tried a million other things, so I searched around, and found this...http://support.microsoft.com/kb/925896/en-usAfter doing it exactly, It FINNALY worked! Lemme know if it fixes ur problem too. :)

If that one ddin't wrk, hopefully this one willhttp://www.gamespyarcade.com/support/firewalls.shtml

I keep getting this error"You have been disconnected.... You may be already be connected using another computer".or something like that.This has become so common, I am unable to use the multiplayer anymore.Manny

>"You have been disconnected.... You may be already be>connected using another computer".I get that alot too from time to time and i only run FSX on one computer + that noone but me have my login credentials.I found that quickly pressing HOST SESSION allows me to start up a server before i am disconnected :(

Yea it's a VERY common problem, and hopefully microsoft will release a patch that will fix the #### thing, because it's really annoying! :)

IF it is really checking for duplicate connection, it should give us an option to Kill the other connection and activate the one you are trying to connect.MAnny
