"Error during simulation."

[ichosethehighway]

Hello everyone

This is my first post, and I'm working on my first individual project in Alice. I put this together last night and ran it on my work computer, and it was just fine. I saved and closed the world, sent the .a2w file to myself in an email, and when I tried to open it up on my laptop at home, I got an "Error during simulation." message. It happens when world.BunnyMove is running, while the first bunny is kicking. It is now doing the same thing on my computer at work even though it was running just fine last night. Can anyone tell me what exactly is wrong with it? I am using Alice 2.2.

Thank you. And please excuse my cheesy program.. it is my first attempt.
