The import/export feature would be nice. I guess right clicking on the folder and 7zip'ing it, is the definitive solution, for now, until an automated process evolves.
According to Christopher's answer that it seems to be an isolated incident, I'm wondering what is it about our particular systems that is causing this purge? 
I have it running on both W7 and W10 and it purges on both. Both OSs are clean installs. Both run the same EVO500...alongside a WD spinner. Both are Dell. It seems to me that the purge is triggered by some integral part of the software once it's updated. Like an auto purge feature.
I'll be honest, I think most people are too lazy to sign up and post the issue, which makes it appear to be isolated incident, but I believe this is happening more often than we think. 
I'm on a lot of forums, and it's always the same people that help developers address bugs, by reporting them. Unless it's a functional problem, it goes unreported.
All of you...know how lazy people are. With that said, I like the idea of an integral backup and restore of the settings.

Same thing happened to me, now twice. There were two updates within the last week, so it seems. Every version of Scanner was the latest at every point of the software running on all my systems. Both times, the previous scan data, after the update, was purged. I don't see this to be such an essential problem but I'm just reporting the observation.

It's $10 off the normal price for a product you don't already own, but $15/each for products that you do.
