Had the same issue ...
... of course when it is a crunch time.
It did work - properly - in ArchiCAD 11.
12 just reports that it cannon communicate with Google Earth. Both 12 INT and GE are updated and current.
I am downloading the AddOn for 13, but doubt it will be different ...
Isn't there anybody to check that the stuff works before it's posted for download? And, BTW - the movies describing the process are still the same old ones from the ArchiCAD 11 times.
