Isn't working

This is the third plugin I have tried from them, and it is also the second to not work! I tried it and absolutely nothing happened. I also tried wishlist, and when you try to go to your wishlist page, it’d be a 404 error page!

For this plugin, it looks like it would work really well for me. When I activated it and changed the settings to fit my preferences, I then tried to do it myself. It did nothing. -_-

I sure hope the people who pay for these get theirs to work.
