windows movie maker

recently i tried using movie maker; i imported a video and was able to watch it using the program, and cut it up into the bits that i wanted. but then when i went to put the parts into the timeline so as to make it one whole movie, it wouldn’t play. there would be sound, but no video. what gives?

is there pictures on the timeline?

My movie is in storyboard (titles, pictures, music, & video) which I watched repeatly while making it, but now it won’t play. The preview screen is black and when I click on “play storyboard” nothing happens. Any ideas?

yes there are pictures on the timeline.
