BackupBuddy for Windows upgrade

I just u/g from a Palm IIIxe to a Treo. Yeah I'm slow. I purchased BackupBuddy for Windows but it is version 2.1.4 the latest is ver 2.1.6. BlueNomad's website is down and no response to email. Are they gone?

The seller just has 2.1.4 in registered ver. I tried to upgrade by installing the trial of 2.1.6 over my 2.1.4 as per the instructions but it does not upgrade correctly. It just changes me to unregistered with the newer version.

How can I get the registered ver of BackupBuddy for Windows 2.1.6 or upgrade my ver 2.1.4?
