I followed their directions for opening the ports on the firewall. I saw that there was an issue and tried that "fix". It solved the problem, so did I do it wrong? Maybe, but others have the same problem? I never had to play with the firewall before this last patch. So I guess that would be my fault. Give me a fucking break
edit: After reading my post without that red rage in my eyes, I can see how people got confused, hell it doesn't even make sense to me. I meant every fix Blizzard posted was tried and failed.
