Re-boot? Sometimes this magically fixes things for me. (Thanks Doktor). Maybe, if you have updated, look at the last Windows update and uninstall it. It sounds like a setting but I wouldn't know which one. The last time I checked CCC was working here on W-10 and 8.1 but I'll check again...
Yes, I'm logged in and online in CCC. IDK, if a re-boot does not fix it.
