Bridge CS2 not opening recognizing .NEF files

I own a nikon D40 which of course saves its raw photos as .nef

I remember installing photoshop cs2 a while ago and having to download a plugin to get it to work with the files. But they have never worked with bridge.

Recently my father was showing me how he uses bridge as its supposed to work. He just plugged in his memory card and clicked 'open with bridge' and it brought up all his raw thumbnails, which he was then able to work with right on bridge. The whole thing looked really convenient and I want to do it. Unfortunately he doesn't know how to make it work for me since he shoots with a canon and never had to install a plugin.

Is there a link to where I can download a plugin to make it work like I did with photoshop?
