Hey guys a quick question, for some reason whenever i try to load any of the l4d2 maps in gmod nothing happens. I choose one, click start singleplayer, and it doesnt start the game. It doesnt crash or anything, but it doesnt load up the map either.
Any ideas as to why this might be happening? Could it be because l4d2 and gmod are different versions of source or something? (read that on the forums)
