Make sure you are implementing the IabHelper.han.handleActivityResult(requestCode, resultCode, data) method in your activities onActivityResult method.

   @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {

// Pass on the activity result to the helper for handling
  if (!mIabHelper.handleActivityResult(requestCode, resultCode, data)) {
      // not handled, so handle it ourselves (here's where you'd
      // perform any handling of activity results not related to in-app
      // billing...
      super.onActivityResult(requestCode, resultCode, data);
  } else {
      Log.i(TAG, "onActivityResult handled by IABUtil.");
  }
}
