why don't you compress the bsp into a pk3 file and put that in the main dir with the other maps?

maybe you put the map in the wrong folder.
maps/
maps/dm
maps/obj
...
when you call a map from the console i think the dm & obj ones have a prefix. dm_ dm- something like that. i don't do that often, i pk3 mine and select from the list.
