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?
