I am running Windows 10 and I had to do a system restore when my computer got funky today. After everything was restored, Thunderbird lost the calendar tab completely. I am pasting the Thunderbird information below and a screenshot of the missing tab. I sync the calendar with Google Calendar, and I really, really need it back. I have tried opening Thunderbird in safe mode, I have downloaded it and reinstalled it, I have deleted it completely, and reinstalled it, to no avail.

I could not attach the screen shot in the initial post. Here is a screen shot showing the tab completely missing.
