It's strange that the "Download ZIP" button doesn't work. Delete any forks you might have in your computer, then with the GitHub app opened, log in on the GitHub webpage and click the "Clone in Desktop" button. You have to be logged in on the webpage and on the app. It should work. I just tried doing it from another account and it worked. But then again, the "Download ZIP" button also worked so maybe your browser is blocking it? You can also try use Subversion if that's what you like.
I apologize, the zip file by itself works fantastically! I've been running this since you uploaded the plugin, I just couldn't get the "Clone to Desktop" through the Windows GitHub app to work at all. Not really a huge issue, I'm just lazy and like to have things auto-update.

Thank you for your hard work!
