DarkRP RP Map Troubles

So, I am trying to put a map called rp_downtown_v4c_v2_roast on my garry’s mod server. I subscribed to the addon to see, and the map works fine. (It is definatley called rp_downtown_v4c_v2_roast) I added it to a working workshop collection which is also force downloaded upon joining, but no help. I checked my web console because it is a dedicated server, and it says in the console “]CModelLoader::Map_IsValid: ‘maps/rp_downtown_v4c_v2_roast.bsp’ is not a valid BSP file
map load failed: rp_downtown_v4c_v2_roast not found or invalid”, so then I GMAD extracted the gma file and got the bsp, and put it in garrysmod/maps and still nothing. (same error) so then i synced fastdl, it synced the map files, butt, still doesnt work. I tested to see if it was a whole server problem by changing the map to gm_flatgrass and that worked.

Please help,
