I saw the announcement about Cakewalk going under and the assurance that the software will continue to work. I only saw those announcements because I opened a project tonight only find I was in demo mode and couldn't save anything. So, at least in my case, the promise that the Sonar will still be usable is proving to be false. 
 
Is any one else having this problem? Any ideas on workarounds or fixes?

Sometimes a combination of running the command center/logging in and out/rebooting can resolve that problem.

Thanks for the response. Someone sent me a PM with a fix and I'm back up and running now.
