You can have three seats (computers) on a license and lots of devices (e.g. lasers) – galvo users have one device per lens, after all.
Follow the instructions on that linked page from the docs, and if you have a computer in there that’s activated but not in use, you can fix that yourself quite easily.

One other thing that can come up is having an expired license. As I understand it, your license is still just fine for any version up to the date it expired. If you check your Lightburn version and go to the archive and download that version, you should be able to install up to a third active seat.
