DoN AI Navigation Help

So I’m trying to install DoN AI Navigation. I’ve been trying to make a flying AI and it does not look like unreal’s usual assets will do it for me. Looks like this plugin is exactly what I need, so I’ll start up a blank project, close it down, create a plugins folder in the project folder, copy and paste what I extracted from the ZIP file, and then start it up again, but every time I do I get an error as soon as it starts up. The error is

“Plugin 'DonAINavigation failed to load because module ‘DonAINavigation’ could not be found. Please ensure the pluin is properly installed, otherwise consider disabling the plugin for this project”
I’m doing this on Unreal 4.10.2. Thanks for the help!
