What version of Camera Raw are you actually running? You can choose Help - About Plug-in... in Photoshop to find that out.
If you have Camera Raw 6.5 or later in the 6.x series (which is what's needed, per the link Mylenium was kind enough to provide above), then we should start to talk about how it is that you've gotten the images on the computer, and how you are trying to open them. Can you please be more specific about exactly what you're trying to do, and what messages you are receiving? Screen grabs are often good, and you can post them here via the little camera icon.
Thank u so
