Revolution slider showing only a grey box

I am having a problem using the “Revolution Slider” that comes with the Moesia-Pro theme. It works fine on the front page, but recently I have created a new slider to be used on one of the other pages of the website and once I insert the shortcode into the page, all I get is a grey box where the slider should be. Could you guys tell me what I am doing wrong? Here is a link to a test page where I have inserted the slider:

I thank you in advance for any help you can give me!

Hello,

You’re not using the Revolution Slider plugin on your front page, you’re using our default slider that’s built into the theme.

Not really sure what’s wrong with Revolution and why it’s not working on the page you linked. Have another look at your settings or send an admin account for me at vlad[at]athemes.com and I can have a look.
