I installed this last night. The help says if ads don't show on your site after 2 hours, contact support. I posted on the forum 3-4 hours later, and here it is the next night, No answer. The re-index button is greyed out, and I saw on their forum LOTS of people had the same problem, yet they never give a solution for it. I uninstalled it. Maybe if you answered support requests, you wouldn't get so many 1 stars.
