"This account needs to be converted to a Battle.net account"
Hey,
I just earlier today DL'd the MoP client and ran a test. The game worked fine, I even made a character, then logged out.
I returned later and tried to log in, but after typing acc + pass, the game said "This account needs to be converted to a Battle.net account" and wouldn't log me in.
close your torrent client> move the folder away from your Torrent's download destination> right click on MoP folder> Properties> Remove "read-only"; then check you are logging by using Warmane AccountName (not Email address) and realmist is setted correctly:
set realmlist logon.warmane.com
