Rev-x au error message, Cubase starts, but error message shows up in Garage Band, blocking startup

Greetings, Gurus!

This may be a Cubase or UR44 issue, not sure?

I’ve had my UR44 for years, so I don’t have the box or the activation #.
Cubase 9.5 Pro starts up.
BUT… Garage Band shows this error message immediately upon trying to start:

I’ve been going around and around with elicenser maintenance, etc. I Updated the dongle, I updated the soft licenser (no products, so whatever…)
Thoughts on resolution? I see while googling that this same problem exists for Logic users, etc.


I think the solution for this would be reactivation of the license, or removing that plugin from your machine. No license is needed to run the UR44 itself.
