The instrument does not open when dragged in the track list. The problem appeared maybe after I downloaded TGuitar and HALion Symphonic Orchetra without having the license. Can someone help? Thank you guys!
Hi and welcome on the forum,
Could you try in Cubase Safe Start Mode [Disable preferences], please?
Hey! I have exactly the same issue. Just started Cubase 12 up in safe mode and it also shows me Halion Sonic completely inactive:
Problem solved by starting up “Steinberg Download Manager” and re-downloading/installing sonic halion SE.
