Suddenly my old D300, which just got a sensor cleaning and check-up at an authorized tech place in NYC, is showing an r12 error in place of the shots remaining number in the top LCD and viewfinder when I press the shutter button. I've remounted the lens, changed battery and memory card and it still happens. It will sometimes fire and other times not. Any ideas? I've no idea what r12 means and can't find it in the manual.
