Yeah, I've sub that. Still no cigar.

Often garry's mod can have issues fully installing certain addons, especially if they have been downloaded via the web version of steam. Try restarting your steam (ending task), reloading up g-mod (seeing if anything downloads upon loading) and checking in game. Repeat this cycle 3-4 times, I have had a similar issue in the past with textures not downloading and this solution worked.
G-Mod just doesn't seem to download everything in one go, it takes a few times.

Let me know if this has been any help.
