Connecting to multiplayer session via lobby

When I join a multiplayer game via zone, the game loads and i'm sitting on the air strip with a big white box in the middle of my screen that says "connecting to multiplayer session via lobby" and it doesn't go away.

What's gonig on?

I've had this problem, but only a couple times in many on-line sessions in the zone. I believe this was due to an error on the hosts connection. Maybe you should try several different sessions, or even host your own and if it still doesn't work then it is probably a fault on your connection/setup, which, unfortunately i can't help with.
