Hi Herb,
Thanks for checking out our plugins!
Unfortunately we are not able to provide technical support here in the Pre-Sales forum, but I would recommend taking a look at the following articles for some troubleshooting steps related to the map not displaying:
Google Maps Not Showing Up
Testing for conflicts
I would also recommend reviewing this article to make sure that your API key is set up correctly.
If you need additional help with this, you can post in our community forum on wordpress.org, which we review weekly to check for bug reports. If you need more in-depth support, you will need to purchase a license.
Alternatively, our knowledgebase is a great place to start looking for answers. You can also search our premium forums to see if another user has posted about a similar issue.
Thanks,
Jennifer
