Unity Navmesh Use

I have just started using the free version of A* with my game. I have a 3D island that I need wolves to be able to navigate.
I created a unity nav mesh, but I cannot import it into the A* object. Am I unable to use unity navmeshes?
Is there a way I can blanket a grid over the world in place of a nav mesh?

I do not have the capability to purchase the full version.

Thank you,
-Ben

Hi

The Unity navmesh system and this package are separate. You cannot use Unity navmeshes with this project directly.
Check out the get started tutorial for how to configure a grid graph: http://www.arongranberg.com/astar/docs/getstarted.php
