Please help! I am using a HP Compaq PC with Windows XP. The camera I use is a Nikon Coolpix E7900. When connecting the camera to the computer, the computer recognises that there is hardware but doesn't load any of the pics on my camera (I have over 600 on there). I have connected this camera to other PCs and it works perfectly and I have connected other cameras to this PC and again it has worked perfectly. I am at my wits end! I would be extremely grateful for any guidance. Thanks very much
