Error during new project creation

Every time I try to create a new project, this is what happens:

C:\Users\Reynolds Family\sites>rails new simple_cms -d mysql       create       create README       create Rakefile Could not find "config.ru" in any of your source paths. Your current source paths are: C:/Ruby192/lib/ruby/gems/1.9.1/gems/railties-3.0.5/lib/rails/ generators/rails/app/templates

Any idea why it can't find the config file? I've done this before and never had this problem. I'm pretty new, though. Thanks.
