Hey Brook, thanks for the response. So I setup a brand new wordpress installation on a completely different server – installed my theme and plugins, and get the same exact experience. This is wordpress 3.9 and still get the Page Not Found error.

I have a custom permalink format, could this cause issues?
“/%category%/%postname%/”
I would be happy to give you admin access if you’d be willing to take a quick look at the WP install and possibly have an idea whats going on with the plugin.
