It's no longer possible to move cPanel accounts as that process required the cPanel servers still be running...those were retired and deleted years ago at this point.
Since it was a Tommy account, we can send an invite to a new address for you so don't have to donate for a new account, but it will be an empty account. If you want to go this route, what email address do you want the invite sent to?
Without the email account attached to the backup, there is no way to recover the data unless Krydos has another way of verifying identity (I'll leave that to him). If you still had the email account, the process would be to verify via email, then download the backup and manually unpack it, request an invite for a replacement account at your new email address, and rebuild the websites on the new account using the files out of the archive.
