Per that error code, it appears that there may be something funky going on in the backend behind your account.
I'm going to escalate this thread to a ticket in our support section to give the admins a chance to investigate the cause of your issue. As a side-effect, this will close the thread. You can get to the new ticket by either clicking on the bar on the top of this page in the forums, or by going to your control panel at

Please note that it could take a day or two for the admins to reply to your ticket, as they are all very busy.
