you seemed to have just skipped over the discussion instead of reading the thread and solution. The OP did not know he could manage the number of seats he has, didn’t now he could ask for an additional seat and didn’t know he could purchase additional seats. Issue is marked Solved.
Maybe @twedlake can also edit the topic title and add " - SOLVED" so this thread doesn’t live on forever. Many LightBurn users here will see that title and do exactly what @jamhot did, ie get behind LightBurn because they are seriously WAY better than the large majority of proprietary software vendors in so many ways, including licensing policy.
