Does anybody use Lowrance's GDM6 to manage/backup their waypoints?

I can not get the software to read points from the sounders SD card and recognise it.

I have updated the Elite5 software to the latest Version3.6, Saved the data from the Elite5 to the SD card in version 2 format, Tried two different 2Gb cards(Kingston and Sandisk), installed the software on two different computers running vista and xp and didley squat.

The software reads the data (goes to 100%) then nothing.... no waypoints, trails or routes...?

Next stop would be to try a Windows 98 computer?

Any info on getting this working would be greatly appreciated

Steve.
