I got a new client (since the torrent's version for some reason wouldn't work.) and I changed the realmlist to "logon.warmane.com" as it says, and then I get on and when I try to log in it says "This account needs to be converted to a Battle.net account. Please [Click Here] yada yada yada"
Did that, changed the realmlist in the config file, and it's not on read only, but this usually only happens when the realmlist is incorrect, from what i've seen anyways, and I am doing the account username/password right.
1. Remove the name of that server on your first post
2. If you can not log-in it means they are using a custom launcher so it will always point to their server, even after realmlist change
3. Solution? go here: http://forum.warmane.com/showthread.php?t=262395 and click on "DOWNLOAD 5.4.8", once on Mega click on "download via browser"
it is an installer which allows to play and download the game at same time
Now, that said, what do you mean for "since the torrent's version for some reason wouldn't work.".
What problem did you get?
