title: Apple's iAd's sample code not working as expected
body: <p>I am trying to implement iAd's in my app and written all the required code for this... But for reasons unknown to me and my pals, my code is not working and i am not able to see the iAd's in my app. Even sample code from apples regarding iAd's is not working on my mac. The same code worked absolutely fine when ran on another system from another location. me and my pals are scratching our heads due to this from the past 3 days. I am posting two screenshots of the same code ran from two different locations and machines.... i am using X-code version 3.2.5, SDK version 4.2, Mac version 10.6.</p>
  
  <p>All the inputs of any kind are appreciated.... <img src="https://i.stack.imgur.com/4DOmP.png" alt="output from other location and system"></p>
