I just went through this, or maybe I should say, am going through it. The latest CR update I can find for CS3 is 4.6 and it does not read the raw files from my 7d. The CS3 is on my old back up laptop but I needed to use it to preview some files and discovered this issue.
Here is a workaround -- Convert the 7D's native raw files to .dng files using Adobe's free DNG Converter. I believe you will then be able to open the .dng files in ACR 4.6 in PS CS3. You can get the DNG Converter version that supports your camera here.
