I am also trying to create a family but get a different error. It comes up with:
Traceback (most recent call last): File "generate_family_file.py", line 22, in ? from urlparse import urlparse, urljoin, ParseResult
I don't know what is wrong with line 22. I tried the trick you suggested above of removing the user-config file first, but it still comes up with the same error.
Any suggestions would be more then appreciated.
