Plutonium

Thanks, it worked

Hello. I downloaded BO2 mainly to play Zombies with my brother, but it is impossible to get UPNP enabled. I've tried every single possible thing (for example, the tutorial that is in this page) and I still can't get my UPNP enabled. Also, we've tried to connect via Hamachi, but it doesn't work and when it does, he goes into spectator mode.
I would love to have a solution. Thank you.
