http://www.adobe.com/support/downloads/detail.jsp?ftpID=2936I had to update mine a few times as well. Make sure that you put the update into the shared folder:
# Exit Photoshop CS2.
# Open My Computer.
# Double-click Local Disk (C:).
# Navigate to Program Files\Common Files\Adobe\Plug-Ins\CS2\File Formats.
# Move the existing Camera Raw.8bi plug-in to another location (for example, a new folder on your desktop). Ensure that you keep this version in case you need to revert.
# Copy the new Camera Raw plug-in, Camera Raw.8bi, from the download into the same folder as Step 4.
# Launch Photoshop CS2 or Adobe Bridge.
Hope it works for you now
