help me please

I tried to play one of my mates online & anytime it went to the 'Select Team' screen, it kept freezing.
I'm not too sure what's wrong as I have no problem playing against other people online - it might take a few seconds to be able to pick a team sometimes but rarely does it stay frozen and then say 'this game session is no longer available' unless the other person exits out the screen. This wasn't the case yesterday as we both stayed in the Team Select screen.
Myself & my mate have played numerous times online against each on different games but don't know what's wrong with playing Fifa 09 online.

uppppppppppp

please need to help:(

I also had UPnP problems with a Huawei router. Couldn't get it fixed :(
