So I found a healer compilation I like but I cant get past the login screen because the compilation is EU. Is there a way past this issue or am I screwed? I changed all the info in the WTF folder and what not. Any help would be appreciated.
Delete the "config.wtf" file in the main WTF folder - that's where info is stored about the login servers and realms.
It won't hurt anything - WoW will remake it with defaults based on your client (so if you're in the US it'll give you the proper realmlist and login server).
