Sorry, I am not entirely certain on what you’re trying to do, If you want to remove the slider from your page, you just need to open/edit your page in Cornerstone and delete the Classic Revolution Slider element there. No, this is not going to affect your content that has nothing to do with the slider.
If you want to import a slider, please download the template Rad provided above.
see the download icon on the upper-right corner
Then follow the How To Import Slider Revolution Sliders guide provided here. No, not the Importing Premium Sliders guide because you need a separate Revolution Slider license for that.
I want to iterate the Revolution Slider that is bundled with the Theme will function 100% without license registration. You can build, import/export a slider with it. However, if you need a Premium feature / Add-ons of that extension then you need to purchase a separate license to the plugin author.
