Directions link returns 404 error

Great plugin, I purchased the Pro upgrade to show my support.

Unfortunately when I click the “directions” link on any result I get a 404 error from Google. I noticed the link produced by the plugin looks something like this:
maps.googleapis.com/maps?saddr=blahblahblahblah

if I change it to:
maps.google.com/maps?saddr=blahblahblahblah
everything works fine
