No, i don't have any firewall activated.

Update: I tried opening one WoW, loging in, flushing my DNS, then trying to log 2nd WoW. Now i get to the "Success!" part but it stays there and i can't access my charcaters. I tried using DRTCP and chaning my MTU to 1400 but still nothing, stuck at success again.

I disable all my port forwarding, reboot my router/modem/pc multiple times and still nothing.

This is really starting to annoy me greatly... Worst part is that it worked perfectly for the first couple of days, and i didn't change anything.
