My computer (and my husband's)stopped seeing my Nikon D70 camera yesterday.It reads it as a removable disk and asks to format my memory card. I don't want to do that because than I'll loose all the pictures of the portrait session. The card reader doesn't see the memory card,and computer suggests me to format it.But I can view the pictures on my camera nad the Demo version of PhotoResque shows me the existing files when I start recovery, but than recovers only the pictures I already deleted a while ago. I need the existing pictures on the memory card. How should I get them?
