Beginner Ruby / MSQL Error

Question

http://localhost:3000/genre

I'm using Instant Rails, I'm introducing scaffolding for the first time ever.

So everything looks like its working fine, I did my own RoR page etc, today i come in today and when I go to localhost:3000 I get the following error message:

Oops! Google Chrome could not connect to localhost:3000

Any suggestions of what I should check would be greatly appreciated. So far I know to confirm that:

1. the windows host file connects 127.0.0.1 to localhost

I've had an update to this the Mongrel server doesnt start properly with the new app I have created, rather than an open window, it just runs a script and closes the window without confirmation that it has started.

Thanks in advance.

here is the details of the Mongrel error:

As it appears your Database has not been configured. Check out the APP_ROOT/config/database.yml file and find if you have created the database that corresponds to the development environment. Once you setup the DB, your code should run fine.
