A lot of replies!
I just got home from today's meeting, and am happy to say that the cam now works. We tried a different computer. We thought that it was some kind of unknown fix, but after reading this thread the real problem is clear: battery! We had been using a backup battery with an unknown charge state, but we charged it today during school. Now we can take horribly-colored photos of everyone on the team (only in bad light)!
I'm still not a programmer, so I can't help with software improvements, but good luck to everyone else. Thanks for your replies.
