iPhone HelloWorld Game crashes in Cocos2d

I just created a HelloWorld app using cocos2d framework. Installation went smooth but when I created a Helloworld project and ran it the app crashes. It loads for a second and then quits.

I am using XCode 4 and iPhone Simulator 4.3. I am not able to find a file HelloWorldScene.m. I开发者_开发技巧ts not coming for me.

Please provide more information: Is there any useful information in the console output? What is in your HelloWorldScene.m? Where does the app crash when you run it with debugging symbols on (ie. "Breakpoints" on)?
