I was able to integerate your plugin into my theme ( pretty easy thanks :) ).
I noticed that your website (http://www.ajaxy.org/) is still using 2.1.4 version of your plugin. While comparing the version on your website and 2.1.6, I understand there were plenty of code changes. as I do not understand php :( a lot, therefore I thought I would ask you this.
The plugin is not showing the popup which it should as it is working in your website (http://www.ajaxy.org). I really like the way it has been implemented in your website. Could you please check this 2.1.6 version, it might have some bugs.
