title: Chartboost sample app not showing Ads
body: <p>I am trying to integrate a tool Chartboost into our game.</p>
  
  <p>We are using following tools for development.</p>
  
  <ol>
  <li>Xcode 5.0.2.</li>
  <li>Latest ChartBoost Library.</li>
  <li>Deployment target being iOS 6.1.</li>
  <li>Base SDK being iOS 7.0.</li>
  <li>Game Engine Cocos2d-x ( C++ ).</li>
  </ol>
  
  <p>In order to use ChartBoost I followed these steps.</p>
  
  <ol>
  <li><p>Created an account at Chartboost.</p></li>
  <li><p>Added an app</p>
  
  <ul>
  <li>Platform: iOS</li>
  <li>Nick Name: Added
  -Test Mode: Enabled</li>
  </ul>
  
  <p>and Its showing the App Id and App signature.</p></li>
  <li><p>Added a Campaign.</p>
  
  <p>-Its On.</p>
  
  <p>-CampaignStart and End are blank, so it will be effective as soon as possible.</p>
  
  <p>-Filter By Bundle verion is Min 1.0 and Max blank .(already tried by keeping both blank.)</p>
  
  <p>-Selected the App I added ,as the app where this campaign will run.</p>
  
  <p>-Campaign Logic: Added test device with UUID.</p>
  
  <p>-Rest of the options are untouched.</p></li>
  </ol>
  
  <p>For test purpose I downloaded and used the sample iOS project provided at ChartBoost site. I replaced the App Id and App signature with my App's ID and Signature.On running the app, it does not display any ads. It logs messages like :</p>
  
  <p>-failure to load interstitial at location Default</p>
  
  <p>-failure to load interstitial at location Pause screen</p>
  
  <p>-failure to load more apps</p>
  
  <p>-failure to load interstitial at location After level 1</p>
  
  <p>I am not able to conclude what wrong I have done! Please help on this issue.</p>
  
  <p>PS:
  1. I have already received a mail from ChartBoost mentioning I have successfully integrated the SDK, and in front of added app , the SDK and Frame icons are lit(green), which essentially shows , I have integrated the SDK correctly.</p>
  
  <p>2.Our game  is still under development and as we are using the Cocos2d-x which is c++ Game engine ,so we will be using some wrapper to call the ChartBoost library. Once we get the idea how it works on native platform.</p>
