Problem at Getting Started guide with: GS.controller.Main

[jerrytowers]

Hi i'm currently making the Getting Started App Tutorial, and i'm at the point of creating the controller, but when i try to run it on the browser i get the following error, and the app gets stuck at "loading":

Uncaught Error: The following classes are not declared even if their files have been loaded: 'GS.controller.Main'. Please check the source code of their corresponding files for possible typos: 'app/controller/Main.js

Does somebody knows how to solve it?

Error: The following classes are not declared even if their files have been loaded


Possible Causes:
* The class name in the Ext.define statement doesn't match the file name
* The full class name must be used (e.g., MyApp.model.MyModelName)
