Full disclamer: I am brand new to this and so am sharing my experiences. Take all of this with a grain of salt.

Make sure you have the code set to "run on startup" I know this was selected once before, but you seem to need to do this each time you load a program. Second, the classmate seems to need to be connected and you need to log in under drivers station in order to get things to work. I'm very new to this whole thing and am not sure what bit of magic is performed, but I do know the driver station is critical.

We found this out yesterday when trying to get the joystick input example to work. We had the whole thing working and then it wasn't again. Nothing would work until we plugged in the driver station. Then we could get everything to work. Make sure the driver station is set to the .5 address and the (seperate) developer station is .6

Good luck!
