Cannot run reapers map pack on my server

[killay]

Im trying to play a few maps from reapers map pack like saloon and i can get the map loaded up onto my server but whenever someone joins (even myself with the mod already installed) it says invalid dl response. I even tried adding t4m to my client to see if that fixed it but no dice any advice? Do the plutonium t4 servers just not support map packs? to add to this the original maps are no longer downloadable after the pack release unless i just cant find them so this was my last resort.
