Login error

I just downloaded a fresh copy of MoP. When I go to log in it says I need to convert to a battle.net account and I can't do anything else.

What am I doing wrong?

Thanks

Login with username.
Make sure your realmlist.wtf is set correctly to logon.warmane.com not .ru

I was looking for a realmlist file, didn't realize it was merged into the config. Thanks.
