Since 2017 update my sync is broken

Since i did 2017 update, now I have little red triangle telling me couldn't fully sync my CC files.. Now I haven't added anything in there. Its same as before the update so now I don't know why its showing me this.. Also when i try to sync setting from premiere and AE it keeps saying"sync failed" So it looks like my sync is broken.. I signed out and signed back in, however it didn't help..  Any help would be appreciated.
