not authorized to send even after upgrade

Hello,

I had an account a year ago with adobe sign. I used it for a month then I cancelled it because I didn't need it. now I reinstated, upgraded again, but can't send documents. there are no "send" tab on the dashboard. it says contact the administrator. but I AM the administrator of this account. what is happening? I have to send a document to sign asap, I don't have time for this I'm sorry. Please advise.
