I keep getting/inviting people but it always comes up error =[
aren't infinity ward trying to fix this?

They're obviously trying to fix it. Just be patient.

Are you sure? *bleep* all word on their official forums.

They're hardly going to let people be unable to join their friends' parties. If they're not working on it, they will be soon.

You'd be surprised at how little some developers will do after the game's released

But yeah, it should be fixed soon, just annoying that nothings been said about it.

Well we saw how quick IW dived all over the people who were hacking MW with the noclip glitch, so I don't think it's really fair to lump them in with the lazy arse developers who do *bleep* all.

I was looking forward to playing Special Ops with a friend, hope this is fixed soon.

Heck, it could be a NAT issue at your end rather than the glitch which others are experiencing.

Right here we go,

Everyone you want to invite as to leave muliplayer
Sign out of psn
Sign back in
Go into multiplayer
Invite friends
Done

Does everyone have to sign out of PSN or just the person who is making the party?

Hope they get it sorted, don't want to having to do that everytime

We had it work both ways

Hopefully they will get a patch out within 48 hours and it will be sorted. IW are pretty good for getting these things done quickly

Hopefully, they do seem to get their shit together quite quickly. Thank god it isn't made by EA!
