Guys make sure you only have the one realmlist in your data > enUS (or the Europe equivalent) folder. Store backup realmlists and stuff in a folder on your desktop just to be safe if you need one.
Alright, so it still isn't working, i tried, re-patching, renaming stuff in Data realm list, it says "Unable to validate Game version" when i attempt to log on, im on patch 3.03.
