In another thread ( https://www.3cx.com/community/threads/trouble-updating-new-service-pack.46777/ ) I asked about updating to a new service pack. In a pm, YiannisH_3CX helpfully explained that I had an in between version that probably can't be automatically updated, and he suggested I back up my setup (other than fqdn and license info), uninstall 3cx, download a new version of 3cx, reinstall it and restore from my backup. That worked fine, but left me with the free license rather than my paid pro license. How do I now move back to my paid pro license? Thanks.
