Slider revolution not loading

I just installed the Fortuna theme. The revslider won’t load. It ones asked me for a license but told me it could verify the license. It is supposed to be included in the package right? Now whenever I try to click on it, it will freeze. Already tried to deactivate it, clear my cache and deactivate all other plugins. Still nothing. I want to import the sliders that are in my package but I can’t. Please help.
