Problem on loading iAids on iPad

I have an application that has a free or paid version which called “Travel Map” (the free of charge 'Lite' edition is actually waiting for authorization.)
It includes iAds to the present version of ‘master’ page, and yes it loads well. When anyone clicks on the ads, it loads well, but at the time of closing, it looks actually empty.
I don’t have the particular iPad, so I don’t understand in the event that this can be a simulator irritate, or even a genuine irritate that’s likely to obtain declined. Has anybody faced this problem and has a solution?
Thanks for the help.
