New account issue

Bought a refurbished dual lite. I set up an account and it says receiver is already on another account. Can’t go any further. Anything I can do or is this a support thing ?
I assume to control and receive remotely off my home network I need the account connected.

This definitely sounds like a support thing. Use the following link to contact support:
