Adobe Camera RAW???

Right oh, I'm after help again.

I finally moved up to the CS versions of Photoshop. I got Photoshop CS2 and thought it'd be a good opportunity to experiment with RAW photos.

I did a wee bit of reading and apparently you just go to the Adobe website, download the latest update of Camera RAW, place the file in your Plugins folder and you should be able to open these files from Photoshop or Adobe Bridge.

Not happening.

Anyone manage this?
