[Request] Bartender Labeling License

Hello friends.
I looking for a license (or license key) for the software Bartender labeling (Made by Seagullscientific).

I did download the version 2016 R9 (the latest from version 2016).
This one is already good enough for me.
There is a newer one 2019, but i not such in a hurry with that.
They all consists in categories: Basic, Professional, Automation and the Enterprise.
I afraid to search on the web to get a wrong key etc.. many virus at the wrong sites.
So maybe some can help for some keys to try?
I would be very thankful.

Regards PAB
