Can't Get Google Client API simple.php example to work - php

Question

Just trying to use the Google Client API to pull traffic data for my site and thought I would try the simple.php file on https://code.google.com/p/google-api-php-client/source/browse/trunk/examples/contacts/simple.php
I've edited it appropriately for my credentials and I can get it to go from the "Connect Me" link to the request permission page, but after I accept I end up at "This webpage is not available". I'm wondering if there might be an issue with needing the token refreshed?
Any thoughts are greatly appreciated. Thanks!
