how to add an additional license?

[uri2510]

Hello
I use the donation version of FFS. I have two desktops, running Linux and Windows and an dualboot notebook, running Linux and Windows, too.
The donation version tells me, that it can only be run on 3 PCs.
What can I do to run the donation version on all 4 "PCs"? How to "upgrade" my license to 4 to 6 PCs?
Thanks in advance for your help.

Best regards Ulf
