Disclaimer -- I haven't looked at your code, I've only listened to your request. It is, indeed, a bummer when (a) the Assignment is Due Tomorrow, and (b) the Hardware is Broken and won't be fixed for weeks.
Your code presumably has two parts -- Acquire Data from Instrument and Do Something Intelligent with said Data. You can't do the first part because the Hardware is kaput, but you can do the second -- all you need to do is to write a routine to simulate the data you expect from your faulty hardware. This isn't as difficult as it sounds -- figure out how many channels of data you acquire, and at what rate, and write a pair of nested While/For loops to generate "known" (but "reasonable") data that you can "wire in" to the Processing VIs. Of course, if your code is not modular, if everything is inside one humongous loop, your unlikely to succeed in doing this ...
