Rated 4 out of 5 stars

This has been a great tool for me in the last few years but now it just does not work anymore.
I tried removing all Google calendars and clearing the saved passwords. Then I created a new calendar, after I sign in from the authorization popup I'm left with a "Locate your calendar" dialog with nothing listed, it's just empty. Suggestion on what I could try next? Reinstall the extension, maybe? It really saddens me that I can't make it work, please give me back my calendars!!!
EDIT: thanks Philipp but I don't have Thunderbirthday installed. All my extensions are Lightning, Clippings and this one.
