Upgraded from Trial to Adobe Sign Individual - can no longer use

Hi, I've just upgraded after my trial sends were used to the annual plan and now cannot use fill & sign from my adobe reader DC on my PC or when I log into Adobe Sign from the website.

On PC, I get through initial email recipients with a message and then get a this error "Could not Send: An error has occurred. Please try again."

On Adobe Sign website - I can choose the document, then choose fill & sign or send for signature and just get a spinning Adobe Sign is loading screen. 

Update: I was able to call customer service and it turned out I had a free account in addition to my paid account. Once they removed the free trial and had me log out of everything, I was back up and running.
I've been trying to get this two work for 2 hours, any help would be greatly appreciated.
