Calendar no longer working after upgrade from 13.04 to 13.10

[Aere Greenway]

Thunderbird no longer reminds of recurring events, and can't see any events scheduled, as if the calendar entirely disappeared. Cannot schedule new events. In edit...preferences...calendar, it appears to be unaware of the time-zone. The button to press to specify the nearest city in the timezone is only 1/16 inch high, and doesn't function.

Expected behavior is that after upgrade, the same calendar I was using on 13.04 would be used an 13.10, or at a bare minimum, I would be able to specify a new calendar (which I cannot).

I need to have the calendar feature work again.
