This just occured today, and worked fine yesterday. I attach camera via USB from camera and also a card reader. Both times it says there are no pics in card, but I cn see the pics when viewing them in camera. Nothing new has occurred to change why it wont let me import my pix. I use XP, and have a Canon Rebel XTi.
First of all, do not save any new file to camera's memory card. Take out memory card, and connect it to computer using a card reader. You should see memory card shown as a drive letter (like H:) in Windows Explorer.

Try a system restore back to BEFORE the problem and see if that fixes things for you... Some HELP in posting on Computing.net plus free progs and instructions 7 Golds
If you try a card reader instead a direct communication with the camera ,you may get an easy solution with this .You just plug in a memory card in the system and next you will get a drive shown through the icon there .Double Click on the drive to fetch data from this.
