Htc ten , not letting me setup again

My HTC ten has gone crazy. I performed a factory reset and it has gone back to setup however when I enter my google account and password it tells me that I need to use one of the user accounts that were synced with the phone before reset.
The google account is the only account that was synced with it.

It won't let me pass this point so my phone is rendered useless.

Please help...
