Hello, so I'm trying to play some cod waw co-op zombies with some irl friends. We're three people, and for two of us, it works fine, but the third guy can't join. It gives him the error 'Connection no longer available.' We've tried the following:
Turned PunkBuster on
Created a new in-game profile
Restarted the game
Verified the integrity of the game cache
I've also port forwarded and opened connections to the following ports:
UDP: 3074 and 28960
UTP: 28960

But alas, nothing works. Does anyone have any ideas?
Thanks!
