Cforms and WordPress MU

I am trying to use cForms plugin to make form on our main community blog, so I uploaded the plugin files to the Plugins folder (since admin only can use this plugin), then I've set a form, included it in one of the site pages....problem is that now the form appear without any styling!

I've tried to change the form style but nothing error message or anything

So can someone please help and tell me what I might be missing here?

Thanks in advance for your time
