I’ve personally never ran into an issue like that. It’s worked perfectly fine every time I’ve used it – http://demo.appfinite.net/epik/
The Theme itself shouldn’t be causing the issue, since the Plugin is separate and works on it’s own. You can actually use any Slider Plugin you want if you don’t like the Genesis Slider.
I can instantly find out what the issue is if you can create a Temporary Login. If so, just make sure and check the box here in the forum that says “Set as private reply” and I’ll be more than happy to take a look.
