I have had two problems downloading to the robot.
The first was fixed by going to legoengineering.com and installing the patch found there.
The second I discovered was a missing wire in the program that robolab somehow missed and showed the run button as good, instead of a broken arrow. After fixing the break it worked fine. in neither case was there any error message.

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?
