Now, why can't you load the JS from your own site? It's not sufficient to have the folder and file with 0755 permissions. You also have to make sure that your .htaccess file doesn't disallow loading stuff from the media directory. The easy way of finding out if this is the case is to enter the JS URL in your browser. If it throws a 403 or 404 error message, take a look at your .htaccess files.
