Node.js fails recognizing a new module

[Working on Windows, with node 0.10.5]

I'm trying to build something simple with the formidable module for node. I installed it globally -

npm install -g formidable

npm http GET https://registry.npmjs.org/formidable
npm http 304 https://registry.npmjs.org/formidable
npm WARN engine formidable@1.0.13: wanted: {"node":"<0.9.0"} (current:{"node":"v0.10.5","npm":"1.2.18"})
formidable@1.0.13 C:\Users\me\AppData\Roaming\npm\node_modules\formidable

Now, the module was installed correctly to the aforementioned directory, but node won't recognize it:

D:\Work\Node\Test4>node index.js

module.js:340
    throw err;
      ^
Error: Cannot find module 'formidable'
       Blah blah blah

Now, my questions are:

1. Is formidable not being recognized because of the version?
2. If not, what could be the reason for it not being recognized?
3. If so, can I do anything about it other than downgrading node or waiting for a new formidable version?
