NOTHING I download is working.

I honestly don’t know if it’s something wrong with the file (which it shouldn’t be, since it’s stuff from garrysmod.org), or if it’s my GMod, but nothing I’ve downloaded today is working right. If the file has an info.txt, I put it in the addons folder, if it’s just models and materials, I extract it to my garrysmod/garrysmod folder. However, once I boot up my game, it doesn’t show up as a spawnlist, in the Browse/All tab, or when I search it.

I really need help with this, and any would be appreciated.

Hm… Did you try Verifying Game Files through steam or defrag garrysmod?

Most addons have a folder which has an info.txt inside it. Make sure you put the actual folder that contains the info.txt inside addons, not just what’s inside the folder with the info.txt
