OK, thanks, I tried to attach the small file to the post, but didnt find any possibility. I made this file in 2008 (as juergenss) and I remember that the updater did not flash the rgn file under Windows higher than XP. Of cause the BAT runs on any windows but the "updater.exe Atlantikbasemap.rgn" therein only starts updater but then it does not write into the device, probably because the communication to the device wont work.
