For future reference, there is a forum section specifically for the Arduino Engineering Kit, where this sort of question will be more likely to be seen by the people who can help you: http://forum.arduino.cc/index.php?board=124.0
I have already requested that a forum moderator move your post there so you should not create a duplicate post.
I would also suggest that contacting customer service via:
is the best thing to do. Generally the people on the Arduino forum are just community members volunteering their time to answer questions, not Arduino employees. Arduino employees do currently monitor specific forum sections so I think you'll be likely to get an official response in the Products > Arduino Education Kits > Arduino Engineering Kit forum section.
