Server Problem Downloading

My server will not let anyone download ANYTHING but the current map, So If I put a gamemode in, It will not let the person download it so when they get in they get this:

Couldn’t include file ‘DarkRP\gamemode\cl_init.lua’ (File not found)



********** COULDN’T LOAD GAMEMODE!! **********



There was a problem opening the gamemode file ‘DarkRP/gamemode/cl_init.lua’
