[gogina]

me and my friend are also getting this error when we go to play private match. one of us usually creates a private match then the other joins through friends list / friend invite. now out of no where we get this error. we've tried doing it normally through our regular internet and over hamachi. we tried with fire wall off, nothing seems to be working.

It's weird. My dad and I do not have this issue. My friend did not until after the update. So now he cant join any black ops 1 servers.

Have this issue as well. Can't join any BO1 servers.

I had him test making a new account. With the new account he is able to play BO1. Logged back into his old account and still cannot play BO1. None of us have been on Plutonium long nor done anything wrong(that I know of).

I keep getting this now, unless you select a default class. How we fix this? t5 is so broken now.

i fixed it, to remove the error you have to make your username shorter, i know it sounds silly but it worked for me

[xPaPaDx]

Yeah mine still does it when I try to re-join a server after leaving, doing class work, then rejoin... I get the NO or bad addy error
