Maybe it knows which filenumbers to show? Take a few pics of a random object, note file names and location on the card. Rename the brides files to match these names and drag the files onto the card and select "replace? yes to all". This might fool the camera to see the files.

If it does not work you are dead meat. It was fun to know you.

NOTE are you sure you see all the files on the card (also hidden & system)? This can be set via folder properties. Also check file properties match whatever the camera expects to find (e.g. not hidden or read only?)
