Can't get simple google client API example .php

Just trying to use the Google Client API to carry traffic data for my site and thought I'd try the simple.php file at https://code.google.com/p/google-api-php-client/source/browse/trunk/examples /contacts/simple.php

I 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 agree, I end up with "This web page is not available". I am wondering if there might be a problem with the need to update the token?

Any thoughts are greatly appreciated. Thank!
