Requires key for some scores, not others

I had Dorico 3 installed on my Mac Pro and a trial version on my laptop. The laptop is gone now.
I copied the .dmg file used to install Dorico on my Mac Pro to my new Mac mini and purchased another Steinberg Key. I transferred the license from my Mac Pro to the Mac mini and added the key.

While I can create new scores, Dorico asks for an installation key when I attempt to open a file created on my laptop using the demo version.

Puzzled. I though the new key would resolve the issue.

Sorry that you’re having problems. Can you be a bit more specific about exactly what message(s) you’re seeing when you start Dorico on your computer? If you run eLicenser Control Center, do you see your Dorico 3 license shown in there?
