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!

Allow me to clarify other's responses.
 
When you build your program in the NXT-G software, you are making a "source" program that includes the icons, their arrangement on the grid, their values, comments and all the other parts of what you think of as your program.
 
When you download it to the NXT, the NXT-G software "compiles" your source program into something known as "object code".  This is a rewriting of your program into thousands of little instructions telling the hardware what to do.  If you use another NXT software program, such as Robo-C, the source code will look wildly different even if the object code does the same operations.
 
While the NXT allows you to upload a program from the brick back onto your computer, this is only the object code.  The object code can be downloaded onto any brick and it will run just fine, but you cannot "decompile" the object code to recreate your source program.
 
This is why any experienced coach will recommend that all programs be backed up after all practices.  We usually just copy them onto a thumb drive into a separate directory named for the date of the practice.  This also lets you recover programs that were accidentally deleted.
 
Sorry for the bad news but hopefully others will have learned from this email thread.

My students lost a program from the computer, but still have it on the robot.  We haven't been able to load it back on the computer for further work.  Can anyone help?
