You are using the security token tied to your FF11 account? I would not be surprised if you found a bug in the system because it was tied to your content ID from 11 - especially not surprised considering the cluster fuck that is converting POL accounts to SE accounts. I would suggest just trying to reactivate your token on your 14 account separately... but obviously if you can't log in you can't. Have you tried logging in without the token? Even through your account is not longer active for 11, have you tried converting from POL to SE and seeing if that clears it up? There's so many things going on right now with accounts its really hard to pinpoint the issue :/
