Another piece of data that might be involved with this problem. I notice that when Cubase 9 is initializing, it always quits when it gets to Halion Sonic SE VST3. Furthermore, when I recently started Cubase 8.5 to work on a current project, I got an unexpected eLicenser warning that there is no license for Halion Sonic SE 2.x. This is a bit confusing since Halion Sonic SE is packaged with the Cubase software and doesn’t require an eLicnese license. Hmm, any thoughts?
