Got a few pics on my walmart cam. I downloaded the software and tried some test pics. worked fine. After 3 days in the woods with no rain I brought it home to check. Cannot get it to work. Directions say plug usb into cam then computer then turn on cam. Autoplay will not work on my com so I have to go thru start, computer, then removable disk. At the removable disk it hasa pop up that says could not be performed because of I/O device error. USB on computer is fine cause my other personal camera works. What could be the prob? Do i need another usb cable? I'd really like to see what's on the cam. Thanks for any help.
