Error: Another copy of this software is already running on this network.

I've been getting this error for the last week:
"Another copy of this software is
already running on this network.
You cannot concurrently run multiple
copies with the same registration code.
Host name: xxxxxx-MacBook-Pro.local.
IP address:xxx.xxx.x.x

I've restarted, removed the app and reinstalled it—entering the license again—but I still get the same error message.
Any advice is appreciated. Thanks

Hi Greg, it means you have more than one instance open on the same network. Check that you do not have QMidi open on another computer connected to the network or that you do not have multiple copies open on the same computer.

Thx Claudio. I should have known that I had it running on another laptop. Always blame User error first lol
