Plugin is not working

I installed the plugin and tried resitricting a page using the metabox options of Subscriber level and I logged out and tried and I am still able to access the page and see the content.

Website page is http://www.g-kidd.com/site/galleries/marc-athens/

This should be currently set to only be viewed by subscribers.
