so for the last month or so i've randomly had more and more issues joining xbox live parties and games.
today specifically. couldnt join a friends game on codmw3, unless one of his buddies joined the party, than invited me. it's more with cod, but i've had issues with portal 2. the only game i have zero ISSUE with is gears 3. someone invites. i can join.

anyoen got any ideas.

It comes and goes. I used to have the problem with one of my IRL friends when joining and then it just started working one day. Same happened when Phazz usually sends me an invite but I think I can join him now.
