I was shooting tethered this weekend, my student turned off the power to my D90 without stopping tethered capture first. It took an hour for lightroom to recognize to the camera again. Later during the shoot the battery and again it too for ever for ever for lightroom to connect to the camera again. Anyone else experiencing this problem? How do I solve it? I have two long shoots (10+) hours this weekend and cannot afford to waste time waiting on the camera to reconnect to lightroom. I am using Lightroom 4.3 and my d90 has the latest firmware.
