I had been struggling with the same issue. This is THE solution what was written by an other user (gegmar) on 15th of Oktober 2014:

"Since I read a lot of ratings complaining about issues with Google's Authentication service, I want to share my solution to this problem:

After updating to version 1.0.1 my calendars stopped syncing. So I first uninstalled and reinstalled the addon and then deleted my google password from the thunderbirds known-password-list (Extras->Settings->Security->Passwords->saved Passwords).

Then - after deleting all remained old google calendars - i added a new google calendar. The Addon asks for Authentication and then provides a list of your available calendars.

I hope it helps some of you with this issue. I really like this Addon because I have not found any other solution, that allows me to write to an online calendar (very useful for calendars used on muliple devices)"
