Power Slider

Permalink
I purchased Natural Concrete theme from the market place. I need to make modifications to the Power Slider that came with the theme, but since I was included, when I go to the support link for Power Slider, it tells me support is only available for persons who purchased the Power Slider or those involved in development. Where can I go to find documentation on this Add-on so I can try different transitions, change the speed and size of the slider, etc? I have tried contacting the developer of the them and have not heard back from him in a couple of days. If anyone else out there can help with modifying this theme, I would be more than happy to pay.
