I've had many problems with joining same Ranked matches. And other people joining my created game.

Its seems, the problem is the new PS3 2.80 Update. Some people have it, others dont, as the PS3 doesnt automaticly tell you to install it.

After many people installed it, they suddenly WERE able to join my game, and I theirs.

So hopefully, many members will read this and ALL install the new update. Then that (little, but very anoying) problem will be gone.

Happy gaming!

Anyone tried this yet? Seemed to work.
