Demo import error – Missing Layer & revolution sliders, demo images, blog/notes posts, products and widgets

Hi,

We’ve successfully installed the theme and demo content, but can’t seem to get the slider functioning. The error message reads: “Revolution Slider Error: Slider with alias classis-clider not found.” We have looked through the documentation and in the revslider example zips and can not find this slider or any reference to it.
