This is a known issue - whatever the Message of the Day states is the server you will be logging into. If it's not changing, you'll need to completely close the game and restart.
Server select is stuck on "North America," right next to it on the Announcements, it is stuck on saying "European.." megaserver. Server select doesn't switch away from NA. Able to login into EU server, but not NA. Been this way so far all day.
