When this happens it's usually when folks forget and try to login with their email address instead of their account name.  Also, some browsers seem to add a blank space to the account name if you have it remember you and that will cause the login to fail.  There is a timeout period and then it will reset itself but I don't know how long that is (and it's not published so the DDoS idiots don't know).  Wait a while and try again making sure to put in your proper account name or send Kano a PM about it.

Interesting, I just did a search on the Stats page and I can't find Luggyman.  Are you sure that is your account name?
