Ann,
Look in the PhotoShop plugins directory and see if you have a file called "Camera Raw.8bi". If you don't, you will have to download it from the adobe website...the following will help you get there quickly:
Enter "Camera Raw 3.4" in the search window at the upper right on Adobe's home page (
)
A list of matches will appear. Choose one of the first two depending on your computer type (MAC or Windows).
Another page will appear about Camera Raw 3.4....scroll down to the "Downloads" button and click.
Download and save the "ZIP" file.
UnZip the file and copy the file "Camera Raw.8bi" to the Adobe "plugins" directory.
I was surprised that CS2 didn't come with this plugin...I contacted Adobe Support, and they walked me thorugh the above to download it.
Hope this helps.
