Things seem to be working properly, but getting this License_error message now. Had a Hyper-V host crash and dirty shut down of our 3CX VM. IP is the same, but looks like MAC is assigned dynamically. Is there any way to view the MAC i am registered to so I can set it to a static MAC on my VM, or can I re-register and wipe out the old MAC registration? I have contacted reseller but no response yet.
