title: AdWhirl and Admob
body: <p>I have downloaded the latest AdWhirl and AdMob SDK. Read and done with the instructions in the AdWhirlSDKInstructionsforiPhone.pdf</p>
  
  <p>I have the following errors:<br>
  1. AddRunningClient starting device on non-zero client count<br>
  2. Unable to fill ad request.  This is a common situation.<br>
  3. <code>&lt;AdMob&gt; Must implement required method -currentViewControllerForAd:(AdMobView *)adView in your delegate.<br>
     &lt;AdMob&gt; The AdMob SDK requires a valid view controller to be returned from currentViewController (AdMobDelegateProtocol).  Cancelling ad request.</code></p>
  
  <p>What can be the problem? Please help me.</p>
