So all of a sudden my D60's playback function won't work. It says that the feature won't work with the current settings but I hadn't messed with the camera settings. I've tried resetting it via the two green buttons for 2 seconds... and the reset button in the "USB" compartment of the camera. When I pressed the button, it prompt to update time and the playback function was available again (as well as the format card function) but once I took a picture, those functions went away or are inaccessible again. Any ideas?
