I have a SLR Nikon N6006. For some reason, when I try to load the film, it takes the initial 2 pictures to get the film on the loader. But when it does it, it sounds like its struggling, and then the LCD readout says its the end of the roll. I have no clue how to get it working and I've already wasted two rolls trying to get it to work. I gotta get it working so I can take pictures tomorrow when our class goes to the zoo. Anyone know what to do?
