I've been using the camera for vacation photos down in Florida. It's a second hand camera I bought at a local pawnshop - all in all it's worked pretty well until now. I loaded a new roll in, Kodak 400UC (36 frames). I'd only shot four of those when the film icon appeared and the frame number started flashing, signaling that I needed to rewind. The low battery icon also came up, so I figured I just needed to change batteries. I did, but it still wanted me to rewind. I'm not sure if the film isn't loaded correctly - if it jammed, maybe I could salvage the roll. Or maybe the roll itself was bad. Or it could be the camera malfunctioning. I do know that I don't want to waste 34 frames of quality film nor would I like to lose the four frames I've already exposed, if at all possible. Any advice would be most appreciated.
