How do I restore my calendar - I didn't know it was lightning...
Just installed the latest update for Thunderbird - did not know Lightning was my calendar - restored to earlier version of Thunderbird, but it did not bring up my calendar. How do I get it back?

Install the matching lightning version for the Thunderbird version you are running.
