title: Gamecenter works in sandbox, but not when testing using promo code
body: <p>I am having some issues with gamecenter. 
  When the player tries to connect to gamecenter, an error message is shown in the application. None of the leader boards are showing up either.</p>
  
  <blockquote>
    <p>Error 15 Error Domain=GKErrorDomain Code=15 "The requested operation
    could not be completed because this application is not recognized by
    Game Center.</p>
  </blockquote>
  
  <p>The app isn't actually released, I am testing the "live" version using a promo code.
  Is this to be expected? Will everything work fine once I actually release the app?</p>
  
  <ul>
  <li><p>Everything works fine when I am compiling through xcode or testing an ad hock version in sandbox.</p></li>
  <li><p>Gamecenter leaderboards where activated and included with the version I submitted to the app store for this release</p></li>
  <li><p>The leaderboards for this app are displayed as "live" in iTunes connect</p></li>
  </ul>
