every time i load up the map i get that weird ass textures like you had in the hidden text but i cant fix it at all. any help?

i really want to play this map but every time i download it and extract it it dose not show up in my mods list. do you have any tips i can use to get this to work. thanks.

This map is one of the best maps i played. The only problem is that there are random textures everywhere when trying to play the new version of this map. If you could fix that would be appreciated. Thanks.
