SpaceBuild Not working.

I just downloaded spacebuild(3 i think) from the SVN. Most of the STools work, powered lamp, Supply conector, petrol thruster get Lua errors. I also don’t have any props or maps for spacebulid. I noticed that the things look diffrent than on videos… mabye a diffrent version.
I tried to download the svn for spacebuild enhancement pack hoping it would have props and maps i can use, but after putting the files in their locations i played gmod and nothing was diffrent. I would download Spacebuild form garrysmod.org but it says i don’t own the game :frowning: , and yes i tried veryfing my account.
