Hello Johan ! I have the exact same problem, a couple of weeks with problems and I`ve tried several solutions. Now I know how to make it work temporarily ! the problem is with F-Secure (Telia Antivirus. I have to turn off Telia antivirus, then reboot the computer and directly open Codemeter Control, stop the service and then turn it on again and it doesn´t go to demomode until I restart the virus program.
Propellerhead support is aware of the problem (I hope)
