Garry's Mod Extensions Not Working

Alright guys, I have one for you. My Gmod extensions are not working, I have tried re-downloading all files and even verifying them. They still are not accessible on Gmod. Is anyone else having this issue? and how can it be solved?

Extensions?

you know, AOC, Dystopia, Day of Defeat, TF2 none of the maps or props are available on my Gmod even though the files are present and validated.

Oh, you mean mountable games. Dystopia and AOC are having issues right now (not a GMod problem but the actual games). As for TF2 and DOD, have you mounted them using the controller in the bottom left-hand corner?
