Have 2 computers with Thunderbird (and Lightning) The computer that has lost the Sync'd Calender I see is Beta version 43 while the other computer that continues to show Sync Calenders is just Release Channel 38.5.1.

How to change the Beta back to Release without losing information ? Thanks Robin.

Your Thunderbird profile folder is kept separate from the Thunderbird Program.

You can uninstall Thunderbird via Settings > Programs and Features or if using 'Vista' OS - Settings > Control Panel > Programs and Features.

select Mozilla thunderbird and click on uninstall.

then reinstall from this link:

select the language and correct OS

If you have not done a recent backup, perhaps it might be a good idea to do one now - just in case :)
