Use Warmane account name not your e-mail to log in. If that doesn't work do this:

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)
