(adsbygoogle = window.adsbygoogle || []).push({}); I just tried to go on multiplayer and it keeps saying matchmaking server blabla.
I already restarted mw2 and stuff but my friends can play and i dont.
Yesterday everything worked well but i did prestige hack for the first time, does it have to do with that?
Help me please.
(sorry for my bad english)

Reset your to make sure your NAT type is open. I'm pretty sure it's got nothing to do with the prestige hack

Well, I don't have NAT open and I can still play.

B-)

Still doesnt work i also rebooted my modem.
;'(

Sometimes this happens, like what happened to me a month ago.
You can wait it out though, it should work the next morning maximum.

try with a different account

Already tried.
Doesnt work either.

Ok so i looked what the problem is and it says it has to do with the PnuP or something, i dont know what that is?

Do you mean UPnP?

I can't get that to work, I just can't.
Oh, I'm having the matchmaking thing right now too -.-

Yea UPnP
My ps3 says that that is the problem.

Something about UPnP in network settings, check that out.
