Within Photoshop go to the "About Plug-in…" menu item just below "About Photoshop" to find the Camera Raw version number. On which menu that is depends on your platform, Macintosh or Windows, which you neglected to mention.
Raw files from your camera have been supported since version 2.0 of Camera Raw for years and years, so it's not a question of your version of ACR. Any version of ACR that runs in CS5 should open those files.
I suspect your raw files are damaged (corrupted).
I am running Windows XP Pro.I am sorry for leaveing that out.These Crw files came right off the camera on to a CD,before anything was corrected.These files will open in photoshop CS2 camera raw.
OK, so am I correct that you have a PhotoCD then?
If so, you should have the Kodak PhotoCD .dll (think that it is a .dll) on the installation disc., and if you install that (think that it was in a "Goodies" folder, but others, with a better memory, than mine, can clarify).
Once you have installed that .dll, you should then be able to Open PhotoCD Images.
Bill, he's talking about CRW. Those are raw files.
