Nope, none of this solves it, the folder is not write protected, the realmlist.wtf is 100% correct and even after deleting the WDB folder and the Config.wtf inside the WTF folder, I still get the official US servers.
The realmlist is correct but when I log in I still get the offical US servers, which are obviously unavailable, thought it would be a problem with the realmlist.wtf file first but it's 100% correct, I've tried pretty much everything but still can't get it to work.
