No picture!

I lost my Windows Movie Maker (classic, which Microsoft no  longer offers [windows essentials]). But, I have tried downloading the program through a few random websites. So far, I've managed to get it downloaded BUT NO picture shows up on the movie screen. It is totally black. The story line shows up and moves along down at the bottom. All the icons and available actions show up.  I have all the slides set up and everything looks good EXCEPT the actual movie screen which is on the right hand side. I've tried every thing I can click on but nothing makes it work. Just black. So, I'm guessing if I save it as a movie on my computer, it's going to be a black video. Any suggestion???
