OS 10.7.5 TB 38.3.0 Lightning 4.0.3.1

Yesterday all was well. Then last night, I Quit TB, closed MacBookPro, it slept overnight. Today, I opened MBP, launched TB, and this time, suddenly, no more calendar or calendar tab showing up.

  • View > Calendar: Calendar is greyed out.
  • Events & Tasks > Calendar: DOES open a Calendar tab, but no calendar shows, except the mention of only ONE of my several calendars in the left-hand sidebar.

If I Ctrl- or right- click that calendar mention in left-hand sidebar, then click Properties or Show All Calendars, then nothing happens from either of those.

  • I CAN export any/all calendars to .html, .ics and .csv, via Left/Ctrl-clicking OPEN white space in left-hand sidebar, then clicking Export Calendar, at which point is lets me choose any of my several calendars from which to Export.

What to do!?

Thanks! Ted
