Hi I imported several clips of one movie to piece together. When I uploaded them everything was working fine. I could see and hear the in the left side preview screen. I had several changes and was just playing with the Movie Maker so I did not save any work to is. I closed the program and shut down the computer. When I returned to start up again anytime I imported a clip to the Movie Maker it does import it but there is no video or sound on the left side preview screen. What can I do?
