I was shooting with our new Nikon 3300 today when it suddenly stopped. So, I turned off the camera, and then turned it back on, but when I hit LV (Live View) I received the message: Unable to start live view. Please wait.
BTW, the battery was 2/3rds green.
Waiting didn't help at all, so I came back to the office and downloaded the photos I had taken. Then, I went to Format Memory Card, but it was grayed out. When I clicked on the gray type, I was told: This option is not available at current settings or in the camera’s current state
