Pandaria Changing from Lich King to Pandaria

[ToMane]

Hello everyone.
I've always played "The Lich King" but today I've tried "Pandaria" and to log in, with the same Account Name and Password, but it doesn't work.
It shows up an error message: "this account needs to be converted to a battle.net account" or it simply freezes in "connecting".

Also i've noticed that the realmlist of the downloaded files was "logon.warmane.ru" and I've changed to "logon.warmane.com" but it doesn't work either.

A little help? :)

Is the realmlist set to logon.warmane.com? If not, change it to that.
Are you using username, and not email, to login?
