Addition to my former text:
I found a way to install Google Calender 1.0.1 (after it was deinstalled):
- download the xpi file from this website
- rename it (simpe name: e.g. Google_calender)
- open addons menu in Thunderbird
- drag and drop the xpi file in addons menu
- restart Thunderbird
- add new calender...

To circumvent problems with the new Google Calender version, I deleted my calenders and I removed the Google Calender addon. Then I restarted Thunderbirg and tried to reinstall Google Calender from the Add ons menu. Now, I'am getting the error message, that Google Calender can not be downloaded :-/.
Has Somebody else this problem or know how to solve it?

Best regards.

P.S.: I really like the new functionality that you can choose the different calenders from a menu! Much, much better then searching for the calender links on the google page.
