Final Cut Pro 6 has a black screen on the canvas and won't display any videos when clicked on. The screen has a grey cross through it with a number in the middle. Could anyone help? The image below displays how my timeline currently looks. Also, this is happening on more than one project, the audio plays but you cannot see anything.
