I've looked this up on the forums and triend to log in with my warmane username and othing happens. When I log in with my email it says it needs to download a patch and then fails. I downloaded both old and normal WotLK clients and have nno idea what to do.
Follow these steps:
1) Restart your PC
2) close your Torrent client and move your WoW folder away from your Torrent's download destination
3) now right click on WoW folder> Properties> remove "read-only"
4) Now you can log-in but by using Warmane Account name (not email address)
