Download / Media Protection Not Working

Hi guys, I've followed the video and manual for setting up media protection, but alas, my URLS are still showing the wp-content/uploads URL.

I need to be able to mask URL's so the user can't copy/paste and email to another person. I want the user to SEE the Media, but not the correct URL.

I have a group set up called "Protected Media" and have assigned two images to that group. The images are shown on a protected member page, but when a member of that subscription visits the page, the unmasked URL is shown. I tried changing the rule to negative as well, but that didn't help.

Can someone please help?
