I am not responsible for any damage occured during your addon downloads. To fix them, visit a tutorial on YouTube or look inside the files. You might have missing files, textures or even Counter Strike: Source. This was made by this random guy called gab! No, this is not made by Valve, Facepunch Studios, or any other developer that worked on Garry's Mod.
It's a major downgrade and it isn't kewl. Absolutely, except for the part of the pirating, don't do that kids.
