Hello,

I'm helping in a Lego Robotics club we have here at the local elementary school. We have one computer and 5 Lego robotics 2.0 kits purchased from the the local Toys R Us. The First RCX we set up with the software worked fine but the 4 other RCX do not communicate with the tower. I am under the impression they need to have there firmware upgraded. if i need to do this how do I do it without reinstalling the Robotics software

Thanks so much,
Noah Melamed
