Space build help

Hello, new to the forum. Have been playing GMod for some years now however, GMod 13 has thrown me a little. One of my favourite addons, Space Build (the props mainly) will not work. I have reinstalled the latest spacebuild pack (as far as I know) in the garrysmod/garrysmod/addons folder. Can anyone give me some help? I have searched the internet to find nothing (at leas that solves my problem). I have downloaded the spacebuild from the workshop, but it only gives me a few props (like 40) and the environment/life support stuff. Thanks.
