Prior to closing my 'Photoshop Elements 10' during early morning of 21st June 2012 it was automatically updated. I believe that it was a 'Camera Raw' Update. Since this latest update I am no longer able to open my Pentax Raw files. This update renders Photoshop Elements 10 useless to me! I have logged onto the Pentax User website Forum for help but as yet nothing has been reported by other Pentax users so perhaps I have received a duff update. I had no problems opening these .PEF files prior to this update! I am tempted to remove the program from my computer, re-install from my original disk and disallow future updates. Please advise me whether this is peculiar to me or is this a known problem with this update.
