server load error (sorry)

Hi,
Just install ruby on the rails in my windows followed by this Ruby on the Rails on Windows (wikis) link.

I installed everything. (in the past I used instant rails version < 2)

but when I was going to load server typing: ruby script/server
the following error was showing:

ruby script/script
internal:lib/rubygems/custom_require:29:in `require’: no such file to load –

script/…/config/boot (LoadError)
from internal:lib/rubygems/custom_require:29:in require' from script/console:2:in

even If I write: ruby script/consol the same error arrived!

If possible then please help me!
