I have a mavica cd350 that was having the same kinds of problems. I used a program called badcopy Pro to pull the pics from the cd using the cd player in my computer. It pulled all of the pics with no problem. A couple of notes that might help. We had this problem after taking a trip and the camera got knocked around on the airplane is my guess. There is a little metal tab that moves the lens that was stuck. After moving the little metal tab the lens was freed and the camera works fine now.
