Hi Ted (et. al.)
Tried working in Finale with VDL for the first time since last fall and I get the error "Missing Audio Units Plug-In - Kontakt 4". The only thing different I believe since last fall is system updates. I have Finale 25.05 and Mac OS 10.13.5. As always, I started by opening one of last year's scores and it wouldn't play. I also did a search of my Mac for "Kontakt" and it did find anything.
Any help would be appreciated. Thanks!
