Unable to complete Slider Import or Widgets Import

Slider Revolution: Can´t find slider revolution import button? If it is the manual import button u mean, I click that but don´t see any files to import…

I also get a message that the plugin is unregistered and I need to enter a license key…Do I need to buy that plugin separately fromn the Theme?

Widget Import: I´ve used the link to download and I get a screen saying the plugin has been closed for download since April 13, 2020 due to a security issue…can´t continue the installation…

Please help. Thank you
