title: Yii Framework Extension
body: <p>I'm currently trying to use the YII Framework extensions. However, I have met up with some problems. </p>
  
  <p>I have followed the step by step procedure in this website: <a href="https://github.com/drumaddict/skydrive-api-yii" rel="nofollow">https://github.com/drumaddict/skydrive-api-yii</a></p>
  
  <p>However, when I call </p>
  
  <pre><code>Yii::import('protected.extensions.skydrive.SkyDriveAPI');
  </code></pre>
  
  <p>in the php.</p>
  
  <p>It gives me
   <code>Uncaught exception 'CException' with message 'Alias "protected.extensions.skydrive.SkyDriveAPI" is invalid.</code> </p>
  
  <p>I'm new to the Yii Framework and would need some help. May anyone give me some pointers.</p>
  
  <p>Thanks,
  Chan Yeoh</p>
