Hi Agustín,
normally this problem happens when you have a syntax error or similar  
in your app.py, the object can't be instantiated and finally the path  
to the demo doesn't exist.

Look at the demo system logs. If you can't see it there, just stop the  
daemon and run ./demo.py manually to see the error message in the  
console. It'll say at which line number the problem is.

Good luck!
Miguel
