O.K. I have purchased and installed Photoshop CS2. When I tried to open a RAW file, I got an error message. After much web searching, I found that I had to download the Adobe Camera RAW 3.1 update. I've done that, and installed the new RAW plug-in in the correct folder (I think). NOW when I try to open a RAW file, I get: "could not complete your request because this version of photoshop does not supply the services required by this plug-in module" ????? Has anyone else seen this error?
