im using ghost one and when doing the same as the tutorial shows (go to maps tab choose map and press create map config) i get:
Creating map file cfg for:
LegionTDWar150cp.w3x
LegionTDWar150cp
mapl LegionTDWar150cp
Sending map config command to ghost
Ghost++ didn't configure the map well but you can try using it (it may require editing though).
this happens to all maps
