We are suddenly having trouble with our
robot accepting downloads from our laptop computer. We get an error message on
the laptop computer that says “There is a data wire that does not have a data
source. Error # 5021.” But there do not appear to be any wires that are not
connected!! We tried connecting a different NXT robot to the laptop and we get
the same problem; so we know it is the program, not the robot. We deleted the
program and reloaded it. Nothing has helped.
Any thoughts on a solution or where I can
find a solution?
