As soon as the Ad List closes, the graphics you selected are unblocked on your computer. If you can't find the ad in the Ad List, then your browser's cache probably prevented it from being downloaded in Step 2 above. Cancel the Ad List and repeat the steps above. Read more about how you browser's cache affects ad blocking here . If you still can't see the ad in the Ad List, then the ad might not be a graphical ad.
Some ads are text-only or are forms formatted to look like ads.
Non-graphical ads don't show up in the Ad List.
