Problem With Garry's Mod 10

I recently got Garry’s Mod 10 from steam. I’ve had non-steam versions but they were giving me trouble, but unlike the steam version, addons actually worked. I am unable to get anything I put in my addon folder to work, and even maps I download don’t show up (yes, i put them in my maps folder as instructed.)

I know that I’m not doing anything wrong, but I hope you people can help me. Thanks!

Im happy that you bought it instead of being a cheap pirate.
Also, be sure you dont put them in the non-steam (coughpiratecough) folder.
Correct folders should be in C:\program files\steam\steamapps\ your steamname \garrysmod\garrysmod.
Some of the folders dont exist yet, so you’ll have to make them.
