WPLMS Login page, Padding in course description and Icons

I am starting to configure the site, I would like to have the demo login page, how can I activate it please? The login page I see is very very bad and not working. The description texte of the courses don’t have any padding. How can I change the backgrount ot the description texte? can you help me please? Do you have the activation for Slider Revolution? I sent 3 email but any answer. To bad!
