I'd normally say: post your log, but when it happens with an unmodified script, the crash has obviously nothing to do with the script.

First, de-install Zorro, remove all files, then install Zorro again. Maybe you accidentally deleted or wrote over some essential file or something like that.

If that does not help, I'd suspect the VirtualBox. Get a different Windows emulator and try again. The usual emulator for Zorro is Wine.
