The Login Failure error is caused by either by incorrect information or by login server issues. If you are getting this error, please check these things.
1. Make sure you are using your email address to login, not your Forum Nickname.
2. Double check your password or login name, to make sure there are no spelling errors or extra spaces.
If you still get this error after multiple attempts, the login server may be experiencing issues, so trying to log in after a short wait. You can also check the forums to see if other players are having the same issue at the same time.
