Cubase Won't Open

I just downloaded the latest update of 10.0.30, and now Cubase won’t even open on start up.

“Cubase Quit Unexpectedly”

I have an iMac with Sierra 10.12.6.

Update your elicenser app

Didn’t work.

I updated the elicenser as you suggested, restarted machine - still same problem: “Cubase Quit Unexpectedly” upon start up.

I also deleted the Prefs Cubase 10 folder, but that didn’t help either.

Is there anyway I can revert back to 10.0.20?

It was Melodyne. I had to uninstall it. It will not work with Cubase 10.0.30
