Sorry, you are not allowed to access this file directly

I am trying to install DCG and I placed <?php dynamic_content_gallery(); ?> into my index.php template and I see this message in the page source while trying to use mootools or jquery:
<?
/* Prevent direct access to this file */
if (!defined(‘ABSPATH’)) {
exit( __(‘Sorry, you are not allowed to access this file directly.’, DFCG_DOMAIN) );
}
?>

The permissions on my plugins directory are setup correctly. I can’t seem to figure out why I’m getting this error.

While using mootools I see the blackbox with loading bar and while using jquery I don’t see anything loaded.

Here is a link to the site I’m trying to use: http://sandbox5.2blu.net/
