TTT Weapons in Hammer come up as Errors? Help?

[ZeroPAiN]

Hey guys! I'm having a little issue, and I'm really unsure why.
After adding the ttt.fgd (downloaded from the TTT Website), when I add weapon entities, they all come up as ERROR signs. Ammo boxes spawn just fine, but grenades, pistols, m16, shotguns, anything comes up as an error model!

I'm at a loss! Anyone have this problem? I own all the Source games, so I don't know why this is happening, even have CSS Installed. In game they load just fine, but in Hammer they're just errors! I can' position them at all :/

Are you launching the CSS version of hammer?

Hmm, good idea I could try that one i suppose.

I usually use SourceSDK Multiplayer2013

TTT weapon models use CSS models, so that is most likely the problem at hand.

Make sure you are set up with the TTT .fgd file
