Were you able to install any of the photoshop cs6 updates or is it just camera raw?
Yes I can see photoshop's update along with other plugin updates but no camera raw update.
Try this installer for camera raw 8.3
If the above doesn't work, you could download the 8.3 dng converter and install it.
That installs the needed profiles for camera raw.
8.3 DNG Converter:
Then download this 8.3 camera raw plugin and replace the existing camera raw plugin in cs6 with the one in the zip that you downloaded.
which can't read my camera's raw files.
Which camera make and model?
