I posted the same issue a few days ago but received no replies...
I had opened sonar from its own icon and it went into demo mode.
Then I closed it and opened CCC and after finishing its scans, finally allowed me to open Sonar...
Closing Sonar and C3, I then again launched from the sonar icon and all was fine.
I'm suspecting that buying on the monthly plan is requiring periodic scans to verify membership currency...
This wasn't explained to me very well... Or at least I didn't realize. As I don't always have internet, this is a problem. When I looked for the offline registration, as was explained in the original startup, those commands disappear... So it seems I run a potential of being inoperable if a scan hasn't been done recently enough and I find myself without internet for the DAW...
I'm hoping there's some way to verify registration periodically without the DAW online after the first time as I had internet that day...
I guess these are some issues that hadn't been understood by me...
