On my main iMac desk top with USB drives I have different Mac Operating Systems installed as well as a couple of other computers I use that have Mac Band-in-a-Box Audiophile 2018 installed.

I have run into a situation whereby when I launch Mac 2018 Band it tells me that it will be running in trial mode. When I try to register with the serial number I have it gets blocked.

How many authorizations are allowed ?
