gpligc map file

Is anyone here using gpligc ?

I'm trying to use a scanned map file with opengligcexplorer, and keep
getting a file not found message. This is on Windoze.

I've tried every combination of path, back slash, forward slash,
upper/lower case, etc, with no success yet.

e.g. :

opengligcexplorer --igc-file=tester.igc --airspace-file=cyyz.txt
--map-set-name=ROCKTON.rgb

opengligcexplorer --igc-file=tester.igc --airspace-file=cyyz.txt
--map-set-name=./ROCKTON.rgb

opengligcexplorer --igc-file=tester.igc --airspace-file=cyyz.txt
--map-set-name=/glider/gpligc/ROCKTON.rgb
