I can give you a preliminary idea, but I don't have the details or the names of the parts...

The battery "reporting gizmo" is plugged into the top of one of the blocks plugged into the cRio. If it gets loose the battery reports zero. Like all delicate electronics if a connection gets loose all sorts of things could happen, or not. You must have jiggled something when you drove the robot.

Why that has anything to do with the downloading code part I don't know. Maybe it is upstream on the power or data wires that jiggled something else? Come to think of it, without it does it report zero or nothing at all? Either way, jiggling the robot must have re-seated whatever wasn't properly set.

I remember last year when the cRio stuff was sent out pre-Kickoff there was questions about no battery reporting, because this one part wasn't included. It finally came with the KOP at Kickoff.
