Gamemode not loading

Error loading gamemode: !IsValidGamemode [btk]
L 07/01/2014 - 07:32:52: Engine error: Error loading gamemode: !IsValidGamemode [btk]

I have garrysmod/gamemodes/btk and inside I have the files btk.txt, init.lua, cl_init.lua and shared.lua

	"title"		"BuildToKill"
	"maps"		"^gm_"
	"menusystem"	"1"

The new one I’m releasing supports this:
