3D FlipBook - Nothing appears

Hi there, I am interested in your plugin and wanted to test it, but I must have done something wrong because it doesn't work. I followed your manual steps and created a book from a pdf brochure.

Then, I tried two ways of inserting the book: directly from the icon and by inserting a shortcode. No matter what, nothing appears, the page remains blank... https://beta.xbee.com/xbee-enzyme-fuel-technology-brochure/

Can you please help me solve the problem? (By the way, I tried with the regular WP theme, the problem remains)

Regards, Ronan
