Well I was about to play with a friend on PSN. When he gives me a squad invite... It gives me a Version Mismatch? What does this mean?

and about Matchmaking...
I always get into a lobby saying... Waiting for 5 more players then suddenly I get into random game for waiting for like almost 30 minutes... Is it about my version of the game? Or Its just a problem in my NAT or a real problem on MP??

On BO (Black Ops), I get into a game fast o.o...
Please answer ASAP or even Cry-Tom. Please answer
Matchmaking on the demo was even faster than my BO experience.

I don't know what it is, but I don't find games that fast either. Most of the time I get put with people from my country or around my country... But at night most of them are asleep, that's when it takes *pretty* long to find a game. Compared to cod where you just click find game and in a blink of an eye you found one.

And my NAT type is on Open, so I don't think it has too much to do with the NAT type, tho I never had to wait for 30 minutes, more like 5 minutes. But 5 minutes to find a match is pretty long if there are so many people that play the game, don't you think?

I have that problem too! This matchmaking is too slow!
It scans for games in our country or near countries, if it can't find anything I think it will go search for other countries!
But it take ages to do that!
Need a fix for that...

i think its the game
