From Upgrading Your Geocoding API Application To v3
Version 2 ("v2") of the Geocoding API was officially deprecated on 8 March 2010 and has now been turned down. As of 9 September 2013 the v2 API will no longer work.
Copy of my answer to: this duplicate question
Api v2 was closed down on sept 13, 2013. Your question was asked on 14th - so that migh be a clue.
What I managed to do is simply modify URLs in googlemaps.py
I changed _DIRECTIONS_QUERY_URL (line 165 of googlemaps.py) to:
_DIRECTIONS_QUERY_URL = 'http://maps.googleapis.com/maps/api/directions/output?'
And it worked fine.
Also I tried modiying line 164: _GEOCODE_QUERY_URL = 'http://maps.googleapis.com/maps/api/geocode/output?'
as suggested here but there's some error, and a) I don't need it anyway b) it's already covered by pygeocoder which is a bit more advanced that googlemaps.py
