the solution doesn´t work for me.
I am stuck at:
Add a new calendar, "Google Calendar, paste the XML Link, click next, give it a name and a color, click "next" and nothing happens. I can click a gazillion times on "Next", but nothing happens.

Not sure where you got those instructions, but the xml link is no longer required. Just enter your email address when asked. If you have the Thunderbirthday extension enabled please disable it temporarily.

I have yet to update all documentation.
