I was out with my RZ67 today and came up with a real issue. I shoot with the mirror up by screwing a cable release into the lens. I advance the film/cock the shutter, compose the shot, I press the shutter button and the mirror goes up, then I fire the shutter with the cable release. That all worked fine for a while then the orange light came on. I switched from a RZ 220 back to a RZ 120 back and it was good till the end of the roll but the cocking lever won't wind the film onto the take up spool. If I pull the back off the camera I can't wind the film onto the take up spool. The indicator window says 10 with the red line so I thought I'd have one more shot. The 220 back says 14 with the red line.

Any thoughts? The manual shutter release works find and the button that pops out with the cable release is in.
