Lua/Gamemode trouble

Well I always took the LUA from the thing i downloaded at Garry’s mod.org

But i download this file http://www.garrysmod.org/downloads/?a=view&id=128074

and their’s no LUA so i cant start it with prop menu

i’ve seen other’s use the add on but they refuse to help!

Anything i can do?

Use the model browser?

Thank you
