Everytime i try to get into a game i get a unable to join game session error. i try all of the options(player and ranked and quick. I sometimes maybe get a game and play that(fun as hell). this happens at least 92% of the time. Anyone got some advice?

Welcome to the wonderful world of CoD2 online. Here, you'll find that Activision has created, quite possibly, one of the worst online components ever for a videogame.

Short answer, the servers are full. There's nothing you can do except play online at 4 in the morning.

Yeah, it sucks. I don't get it as often as you do, but it happens to all of us. You can either keep trying. Anytime you get the message keep hitting 'A' rapidly until you get back to the lobby wait page. It won't help, but you'll get back to the wait page fast.

Or wait for the patch.

Or try out the glitch as it seems to solve other problems as well(16 players, no lag, customize game):

Yep, but your right, if you manage to join someones game its fun as hell *sigh*. I'm only free on sat and/or sometime friday, and I never ever can play a online game on sat. Instead of Activision focusing to make a patch addressing the game save issue they should more focus on the online service they are giving.

yeah.. for being the most fun xbox live game.. its certainly the most frustrating.
lag, connecting issues... its all garbage... the game is so damn sweet.

BF2>COD2 when it comes out

and im pretty sure there will be no patch for COD2 online. activision = full of $hi+
