Just got laid off

I just got laid off and registered. The site said they couldn't verify my SSN, and might need me to verify documents. Cool, whatever. I see in other posts that often they'll send you a message within the application to send documents. Went to try to login immediately after registering to confirm I am able to and I received a message stating "your SSN is not recognized by the system as registered. Please register before attempting to login." So I attempted to register again, and it says my email is already associated with an account (duh). I'm going to call them tomorrow and am prepared for the hell hole that contacting unemployment will be, but has anyone else encountered this?
