addons stopped working

pretty self explanatory. i completely re-downloaded steam and all of my games, and now all my gmod addons wont work. i tried to download some new ones from garrysmod.org, but those wont work either. any idea whats goin on?

never mind this thread, i figured it out. when i re downloaded steam, i called the root folder something else. i was putting addons into another old gmod folder
