I read the installation guide and i did the instalation of the theme and the demo content. I imported all the demo content, the full demo. I installed a new, fresh, wordpress.org installation, 4.7.5

But I have this problems:

1) Using the Digital Agency homepage, doesnt appear the correspondent slider revolution, instead apeears this error message: 

Erro no Revolution Slider: Slider with alias agency-sparta not found. 
Maybe you mean: 'agency-rave-animated' or 'ahegem-app' or 'thegem-app' or 'app-sparta-content-slider' or 'App Sparta Animate' or 'business-02'

2)The menu doesnt appear the "Features" menu and submenu. The menu doesnt have the same appearance of this page: http://codex-themes.com/thegem/agency-sparta/

I did the installation process as it is in this page: http://codex-themes.com/thegem/documentation/

I need help to fix this things. Thanks!
