Aww, sorry Steph!  That's too bad.  I would definitely run the program and
video it, and at least that will give them a skeleton to rewrite the
program.  They  will still have to refigure rotations and such, but you'll
be surprised what they remember!  Our kids have rewritten a program from
scratch, and I am always surprised at how much they remember!

Good luck!
Sonya
