plugin parallax help

Hi I just purchased the following plugin for a website I am trying to do in wordpress

wp-justParallax, a parallax plugin for WordPress

I can’t seem to get the plugin to work when I make new pages

I purchased it from codecanyon, I want to work the same way as the live demo does

Can anyone help please, I am doing it on wamp at the mo

Kind regards

Ian
