The most likely reason for schedules not working after an update is having updated by hand. Use CCC's "Update CCC" menu item - check "Inform me of beta releases" if that's what you want, and click on "Check now". You will be guided to update any schedules correctly for the new version. If you download the new version yourself you should disable existing schedules before updating and then re-enable and save them. Using that menu item is easier! Help is available in the CCC forum.
