Can't use phpStorm running Yii

I am following http://www.yiiframework.com/wiki/92/configuring-phpstorm-ide-for-yii/ guide but i still get 'undefined' method for something like '$this->render('index')'.

I can trace parent class from my project to base class in Yii framework file.

My web structure is :

/Root
     /TestDrive
     /Yii
          /Framework

So in my project, i have only /TestDrive and include Yii Framework as External Library; i have delete Yiilite.php but i can't exclude some folders (step 2 from the guide line)

Please help me out.
