purchase code revolution slider


I bought the silver screen theme which comes with revolution slider, when i go to use the purchase code to activate revolution slider it doesn’t work?

Bundled plugins don’t have purchase codes / they will still work as expected without it https://help.market.envato.com/hc/en-us/articles/213762463-Bundled-Plugins

why does it ask me to pay when i want to use a premium slider?

If you mean the templates (ex. Those that are part of the theme) then those are a feature only included with the stand alone plugin
