LayerSlider WP and Sidebar

Question 1:
Hi, i have bought your template Game Addict, but when i go to the plugin menù LayerSlider the system alerts me “You need to authorize this site in order to get upgrades or support for this plugin. Purchase a license or enter an existing purchase code.” Where i can find the license?

Question 2:
i can not add a widget sidebar to the home page ( I don’t know why )

Thanks, Regards.
