Javascript error

Easy gallery is not working. In Chrome development tools I see this javascript error:

/*
// WP Easy Gallery
// http://labs.hahncreativegroup.com/wordpress-plugins/easy-gallery/
*/

jQuery(document).ready(function(){
jQuery(“.gallery a[rel^=’prettyPhoto’]”).prettyPhoto({counter_separator_label:’ of ‘,theme:’light_rounded’,overlay_gallery:true});
Uncaught TypeError: Object [object Object] has no method ‘prettyPhoto’
});

I’ve installed the lastest 3.8 version.
