Hi,
Please download Recover My Photos from
www.recovermyphotos.com. Put your card in the card reader, run the program and select "Deep Scan" from the main menu.
In the drive selection window you should see your card listed either as a drive letter and/or a physical drive. Select and search one or the other for the relevant file types.
You should be able to find your photos - click on them in the results screen. Are you able to see the pictures?
