After reading all these support posts and not seeing them being addressed let alone resolved, I'm starting to wonder if this plugin is still being supported. It's not working on my site either using WP 3.6.1. No x to close the screen, It pops up on all pages even when not supposed to.
It's a shame as this was a really great and easy to use plugin.
Let's hope the developers get back in the game and update/fix this plugin.
