Start the chat on the computer the printer is hooked to and if you get stuck they can take control of it and do that for you.

I just had that same issue. Started a chat with support and he walked me through removing everything I had installed and removing everything having to do with my old printer.  Then he reinstalled the new one and it worked fine.
