Hello Brennan,

The easiest way to fix this issue is to delete your WTF folder. By deleting this folder, you will lose your settings for any accounts you had that used that copy of World of Warcraft.

This also resets the auto realm select so you can now choose the correct realm when you login.

However, in the future, I would suggest looking through the forums first to find your answer.
