Karen,

The other folks have suggested good ideas... I'd also try using a different
cable, and if that doesn't work I'd try a different PC or laptop.

Please do let us all know what ends up working for you.

Good Luck,
Kevin

Subject: [VADCFLL-L] NXT Robot error # 5021


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?
