Cant get localhost to show “Welcome to Express.”

[Glee02]

Hi all -
I cant get the local host:3000 webpage to show “Welcome to Express.” in chap 1

I think i done everything as per the books instructions up to typing in localhost:3000 into the browser but when i do this it says it cant find jade

Then when i reload the page i cant get anything except

"Oops! Google Chrome could not connect to localhost:3000 "

I have removed the current package.json file out of the authentication file and then copied and pasted the whole package.json code of the book into the file

Then i have cd to authentication and then done the re install of npm install after and node app many times - but with no success
I took off my firewall and still no luck - im using windows 7

My main install is in C:\Program Files\nodejs

and my authentication file is in my working directory C:\Users\newuser\authentication

Im wondering if anybody got any ideas that might help me out here - Thank you

Have you tried copying running the code from the book. i.e. download the book's code, and head in to the chapter01/authentication folder and run `npm install` from there and then try to run `node app` - see if that works.

Further to AussieJohn's comment, does the console produce any output that you would be able to paste?
