Ruby on Rails can't connect to localhost:3000, 127.0.0.1:3000 and 0.0.0.0:3000 on Windows

I'm a total newbie learning Ruby on Rails and using a Windows machine. The steps used to install ruby on rails were:

1. download ruby200-x64 installer for Windows

2. then run the following commands

   • ruby dk.rb init
   • ruby dk.rb install
   • gem install bundler
   • gem install sqlite3
   • gem install rails
   • rails new testapp
   • cd testapp

   • bundle exec rails server which means that I ran rails server in the testapp folder and part of the output says this:

     • Booting WEBrick
     • Rails 4.1.1 application starting in development on 0.0.0.0:3000
     • Run rails server -h for more startup options
     • Notice: server is listening on all interfaces 0.0.0.0. Consider using 127.0.0.1
     • Ctrl-C to shutdown server
     • Exiting
     • C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/tzinfo-1.2.1/lib/tzinfo/data_source.rb: No source of timezone data could be found. Please refer to http://tzinfo.github.io/datasourcenotfound for help resolving this error
     • Follow by more lines of codes (sorry, didn't have enough reputation points to post an image.

3. Finally when I tried to connect to localhost:3000, 127.0.0.1:3000, or 0.0.0.0:3000. None worked. Any ideas? I'm guessing it has to do something with the Exiting line.

The error indicates that TZInfo was unable to find a source of time zone data on your system. This will typically occur if you are using Windows.
