I followed these steps (thanks, Dave Fletcher):

0. If you still have access to your local calendar(s), export its(their) ICS data.
1. Uninstalled Provider and Lightning, shut down TB.
2. Removed the calendar-data folder from my profile folder (one could rename the folder if a backup is desired)
3. Checked my profile folder for any Provider folders or files (I would have removed them if they had been present)
4. Edited prefs.js, and removed ALL references to calendar (there were numerous entries left behind by Provider)
5. Re-started TB, and ensured everything was gone.
6. Reinstalled Lightning. Local Calendar was created (no events).
7. Rebooted TB, just to be sure.
8. Reinstalled Provider, received the aforementioned 'version' error, but re-associated with all my onlin/Google calendars using network/Google option.
9. All events reappeared rather quickly as I reactivated (check-boxed) each calendar.
10. If applicable, import local calendar data you exported previously.
