Gamesalad WEIRD Problem Help??

I was trying to make a game, which had several scenes, and I had a big problem when I went to preview what I had done. When I previewed it, none of the behaviors (like switching scenes with actors) would work. So I tried to go straight to the main scene, since the buttons didn't work, but nothing happened. After that, I tried to preview from the main fighting scene, but it wouldn't work! It's hard to describe, but the actors didn't show up, and it came up with some weird, random image every time.
One weird image that came up when I previewed: http://imageshack.us/photo/my-images/24/screenshot20110521at426.png/
Somewhat what it should look like: http://imageshack.us/photo/my-images/832/screenshot20110521at426.png/
HELP- I've been working really hard on this!!
