Hello, Im sorry they are having issues, did you point them to the
instructions:

Is this issues they are having at home, or at school? If it's at the
school, if I can help you get one working, you can hopefully help them
get them all working. If it's at home, I can try and help on a more
individual basis, but there will be likely a lot more factors involved
with their home computers.
As a reminder, iNXT Remote cannot do direct connection from the iPod/
iPhone to the NXT, it requires a computer to run a server to forward
commands and replies from the phone to the device.
