Please help. I'm new here and am trying to get the upgrades for my A630. I downloaded everything and creadted files as per the popular science article. When I put my SD card in the camera in playback mode and turn on the camera I'm susposed to select "Firm Update" from the main menu. So my problem is when I go to the main menu there is no "Firm Update" for me to select. Can someone help me figure out how to get to the "Firm Update" part of the menu. Thanks. Rick
