(adsbygoogle = window.adsbygoogle || []).push({}); Yesterday me and a friend on psn did the 1v1 demo boosting. he hosted and i joined and did the whole player card thing and pressed x until the game started. problem is, my roommate also play cod and we were trying to do it together and when i host and he goes into his playercard "save and exti" menu and i leave, he is unable to invite me back and vice versa. also, if we try to hit triangle and join in game it won't allow us to do. i'm not sure why we're having this problem and once tonight we've even managed to get the game to start but it wouldn't allow us to choose our class. (again i encountered this same problem with my friend last night but upon further attempts successfully got it to work. If you can explain why this might be happening i would greatly appreciate it.

Hmm, when you said you were trying to do it with your roommate, was that on splitscreen? That might be the problem, otherwise i'm not sure :/
