After the update, allot of PS3 owners are having problems as for some reason black ops changed the NAT type to strict. But before the update, my NAT type was open. And I could have a few decent matches online but now its impossible for me and the majority to have even 1 game online without getting the "lobby closed" notification.
Its trey arch that NEED to fix this, not us. Any other online multiplayer game works, e.g. MW2, GT5.
Someone send JD2020 a tweet on twitter regarding this major problem, coz it needs to be fixed ASAP.
