SANYO VPC-S1070. I changed batteries and when I put them in it asked for the time and date. As I was finishing the minutes it would not let me go further. I turned it off and then back on but it freezes on the open SANYO screen. I tried taking the batteries out, no change. I tried syncing it to the computer, and the computer never recognized the camera was hooked up. Whats wrong and what do I do to fix it?
