thanks
really using snow? hope you like it.
anyway, back to topic; solution is simple but need to follow it cause you must currently have duplicate files in .bgl and .off state
1. First check configuration state (default? snow?) and note it. If no status shown due to duplicate files then just check files in \amsterdam\scenery, which are called "TileMap**". If the snow variation is active (ie ***_snow.bgl) then you can be sure that snow was selected last. If not, then default.
2. Go to your scenery folder and delete all grd_lines*** files
3. grab those fixes from above and extract somewhere; this will give you grd_lines.bgl and grd_lines_snow.off
4. if your setup from step 1 was 'default', then all you need to do is drop new files into your amsterdam\scenery folder. If setup was 'snow', you will need to rename the extracted files before dropping them into scenery folder, as follows: grd_lines.off and grd_lines_snow.bgl
hope this works
