I had a similar problem with the conductor, mine wasn't a card error, mine just reported that it wasn't connected.
I had to use a magnifying glass, some solder flux and a fine solder tip to reflow every connector on the flash card header.
My flash card header was under some tension, when you reflow the pins, they tend to pull OFF (actually they spring up off) the board, so I pushed down lightly on the header pins to get them re-attached to the PCB. It took three or four goes at reflowing, but it's working great now.
