How to recover a lost SetupBuilder license?

Hello:
I am curious, how can I recover lost license information for my SetupBuilder Application? I had licensing information at some point and my email server went down. I have emailed sales as well as support from a new email address and not gotten any response back. I know that Lindersoft is a small family run business, so I hope that everyone over there is doing OK.

On a different note entirely, I am curious what it would take to apply for a job over at Lindersoft?

Any help in this matter would greatly be appreciated
