jax

I have successfully completed the node.js tutorial. I am trying to deploy an express app, and after reading another expressJS ticket I also tried putting the app in a subdomain titled express.jax.heliohost.us. The app folder is at the path - home/jax/node/riddleAdventure. The app url is - express.jax.heliohost.us/riddleadventure. The app has been registered using application manager. Dependencies have been ensured. Yet, the same express-related 'Cannot GET' error is displayed when I visit the url. Please advise, thanks very much! - Jax
