Installing Devise/User Model - Application Treebook no longer opens

Hi, I installed devise and re-watched the video 3 times to make sure I did not miss any steps or code, my application no longer loads the message I get from the server is that it can't connect to the local host. In the video where Jason first types in the code 'rails generate devise user' I don't receive any of the feedback with "create", "insert", etc.,. This is what I receive, if anyone can offer any help I greatly appreciate it because I'm not able to go any further now.

rails generate devise user Usage: rails new APP_PATH [options]

Description: The 'rails new' command creates a new Rails application with a default directory structure and configuration at the path you specify.

You can specify extra command-line arguments to be used every time
'rails new' runs in the .railsrc configuration file in your home directory.

Note that the arguments specified in the .railsrc file don't affect the
defaults values shown above in this help message.

Example: rails new ~/Code/Ruby/weblog

This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.
