The code you'll get off isn't really the code, it's the file that you get after you're done compiling which you can reupload. You won't get the actual code back.
http://www.ifirobotics.com/rc.shtml It's near the bottom, called "Device Reader Ver1.0.1"
If you don't have 2007's actual code which you can recompile, I recommend you construct some sort of organization for your code this year, a version control system is always good, (we use something called Git, I've found most teams use svn (though Git is superior, mwahaha)). SVN is centralized, so you have the server somewhere and you push your day's work up to it. I never liked this.. so Git is decentralized. Everyone who has the code has all the changes ever committed. =D among other things, I just love it.. but that's not really what this topic is about..
(and find who got rid of your old code and slap that person a bit (for me))
