( Hey, on that navicore page... "you can install ... without the windows installer! great !)

From reading the awsomely detailed notes I see that the directory structure of my download was not correct - at least the new mapdata directory was missing the _Germany & Alps bit. I'll go see if rernaming that subdir does the trick.

thanks fir the hint about moving the maps directory. that would be best; most triumphant hints there dubwise.
