I updated to Beta 115.01b and lost my Sent folder, Write a message, Calendar data, and maybe other stuff. I am on Windows 10 64 bit, use POP, and seem to have 1 profile. Tried to do an Import, and can see Address book and local folders now. How can I revert to the non-Beta version and previous profile?

Reverting to a prior version is iffy, but this often works: - exit thunderbird - in the computer search box on taskbar, type: 'Run' 

   select the 'Run' app
   Enter: thunderbird.exe -P --allow-downgrade
   click on 'OK'

If you want to test with beta in future, I suggest not upgrading the release version, but let the beta upgrade to a coexisting location.
