On this one I’d contact Steinberg: https://www.steinberg.net/en/support/usa.html – and go into Chat
OR
Call – You can reach us at 844-358-4022 Monday through Friday 9 am - 7:30 pm EST. Let them take control of your computer.
If you call you can have them take control of your computer and fix whatever the issue is. I had this problem too and they took control and were able to within 5 minutes (watch what they do and ask while on phone any questions) get things nice and ready to go. Number of issues could be issue including demo stuff…
