When you said earlier, "the servo doesn't even move," when you run the program, does the servo ever move at all? How about if you try to force it (with your finger) to go to a different position? When you try to turn the servo shaft to a different position, does it want to "fight back"?

If the servo doesn't seem to be doing anything at all (i.e. when you try to turn it to a different position, it doesn't "fight back") then I would speculate that the problem is that either the servo is not properly wired to the correct PWM output, or a charged 7.2V backup battery isn't connected to the RC. The servo motors get their power from the backup battery (not the main 12V battery) so a 7.2V battery needs to be connected to the RC for the servos to function at all.
