If you are registering a Loginserver username using AOL, cable modem or another wierd ISP that messes up your IP then you might not be able to log in due to a bad user/password error.
If you get the bad username/password error when you try to log in for the first time, Have a friend or online buddy Re-Authenticate the account for you by clicking Re-auth on the account creation page, entering the username and password, clicking Submit and then logging in using the successfully fixed account (has to be done on the same computer that re-authed it.
(**NOTE: Please do not message me with account fixes anymore hehe. I can not handle anymore.)
