Bob,
Your Photoshop is already updated. 9.0.2 is the latest version.
RAW file support is a different matter. Photoshop cannot open or process RAW files by itself. It needs the ACR-plug-in (ACR = Adobe Camera Raw). The version that gets installed upon installation of Photoshop is an old one.
You need to check whether your specific camera make and model is supported by the latest version of ACR, then download the plug-in and install it manually in the correct location AFTER manually removing the old one that came with Photoshop.
Each camera model produces a different flavor of RAW files.
There are detailed, specific instructions on how to install the ACR plug-in on the download page. Print them out and follow them to the letter.
Check the FAQs and the Debugging thread at the Adobe Camera Raw forum. Post there if you have further questions.
