Every time I try to log in with my forum username/password I am told my account needs to be converted to a battlenet account, fresh install of warmane as well
If you can't login do the following-
Have WoW closed.
Open the properties for the Mists of Pandaria 5.4.8 folder.
Uncheck "read-only", hit apply then ok
Open the folder, then the WTF folder
Open config.wtf (with wordpad/notepad), and make sure you have the following line
set realmlist "logon.warmane.com"
If you have set realmlist "logon.warmane.ru" change .ru to .com
Save the file as .wtf
