I'm having similar issues.
I can login to the forum, but when I try to log in to my hosting account I get:
A fatal error has occurred processing your request, please try again momentarily. The error code provided is: Unknown
The support knowledgebase says that if I am suspended I need to log in to my account to unsuspend, but of course I cannot.
I have opened a ticket. I guess I'll wait it out. Once I get corrected I will be sure to pay the $3 fee to avoid suspension too.
