Google maps does not load correctly

I am using Google Maps widget and API KEY for Google Maps. I have an API key, but the google maps will not load. I get a box with an error message where the map should be. It goes to the proper address if I click on the box, but it does not display the map when the page loads.

Hello there,

Try this plugin to fix it, please.

Let me know how it goes.

Thanks Kharis,
I am using API Key but I still have a broken map image. I deleted the API plugin and installed fresh, but I still have the problem.
