I can not download this app.

I can not download this app , because the following files can not be loaded. :(

1. "cdnjs.cloudflare.com/ajax/libs/backbone.js/1.0.0/backbone-min.js"
2. "cdnjs.cloudflare.com/ajax/libs/underscore.js/1.4.4/underscore-min.js"

The page always keep loading status.

How to do it?
