Suddenly Cannot Login

[ErnieKeebler]

Same login details since SE accounts were made available, same security token since they were first shipped.

Get home today and suddenly cannot login to any SE service. FFXIV or Account site.

I tried resetting my password and it prints "The entered password is invalid.
Passwords composed of only alphabetic characters, only numbers, or only symbols cannot be used. Passwords including the same three characters in a row cannot be used. " above the text area for One-Time password.

Any ideas? Am I boned and stuck wasting cellphone minutes on Monday to get everything fixed?



Additional info:
-Was logged into my main account, tried to login on my fiance's, who barely plays and I was going to leech a Teleport off of. Login was denied. Hour plus of frustration followed.
-Win 7, with AVG always on.
-Use Firefox's current version, up to date, with Noscript, ABP, etc.
-I do not visit malicious sites or RMT sites.
-I only disabled said Firefox plugins to try to get password reset working, thinking it was blocking it.
