Map Just Shows Blue Screen

Hello, this looks like a great plugin and I would really like to use it for our site but I cannot get the map view show location. The list and grid view show the added location but the map view just shows the blue backdrop. I have seen a couple posts from people that are having the same problem but they did not post their solution.

Here is a link to the site. LiveRecovery.org

We are using a valid Google Maps Javascript API key and there are no errors.
