FarMap = mapGW_F.tga
I didn't have a mapGW_F.tga file in my Norway folder. Is it possible that this caused the problem?

Sure it is !
(I don't remember i made a few versions of the map....) but anyway, if you don't use "excellent" mode but only "perfect" you may just write instead:
FarMap = map_F.tga
... and it will make it !

(I'll try to remember to add the file in the package).
