Recover lost PVOutput Account

I had set up an account to allow my parents array to log to pvoutput, but due to a server failure we have lost all the account details, and are struggling to recover the account.

We know the System ID, and the serial number of the inverter, which should be enough to prove that we own the system, but the password recovery does not recognize the email address we believe was used to set the account up?

Can the account be recovered?
