So me and my Partner have played black ops 2 a few times together using Plutonium and it's worked fine, but all of a sudden today when trying, We've not been able to join eachother and we've tried many different things that haven't done anything.
Removing and Re-adding firewall information, removing and re-adding eachother, closing and retrying, using hamachi etc. Nothing has done anything yet it worked fine last time we tried to play. I cannot portfoward as we are in University so the wifi we have is just an extended part of a main hub somewhere, which is not something we have access to.
Anybody know anyway to properly fix this or it's happened to you and you found a working method? Any help is appreciated ^^
