Blizzard =/= Security I could not log on after last patch, tried all the "fixes" posted here and on Blue posts. Finally read someone saying it was their firewall software. Turned off my 3rd party firewall and on I went to play. I also have WoW loaded on a laptop. Can't play on it as the GPU sux but it will log on. Started Wow ON that, after the patch got the same cannot connect message. Turned off the firewall (same product on both) and off it went. On the Main system I did try to open the "Blizzard" ports with no luck. So until things are fixed I play WoW with no firewall. Blizzard =/= Security
