Anyone Having The Same Problem On Ps3?

when i try to acept the invitation from a freind to go in a match it says "game session no longer avalible " and then when its loading up the top write it says " trying to join 1 potential match " and then it says the game session thing and the only that i acepted and worked was a invite from SCA Member - Spanks ......

So does anyone no what my problem is? thanks

Yer, I've had that a couple of times.... generally a system reboot sorts it.. hella annoyin though.
