Can't get plugin to work even after following setup instructions

Hi,

I went ahead and added the plugin, activated, added the mpopup and activated the CSS Classes but it doesn’t seem to work.

Here is a screenshot of my settings: https://www.dropbox.com/s/4uofwbgn5fjerp8/Screenshot%202015-04-13%2020.06.08.png?dl=0

Using the broolyn theme: https://themeforest.net/item/brooklyn-creative-one-page-multipurpose-theme/6221179

The menu button that I set up is News Letter
