I have the same problem, I don't know what to do to fix it. I don't really understand the posts that are here? Thanks.

Thanks, it worked.

I will try that, thank you.

So, can anyone help me?

I just reinstalled Garry's Mod and everything is still messed up.

I have no addons installed that would conflict with this.

I have been having problems with Garry's Mod and TTT right after the Steam interface update. Here are the problems: Scoreboard is sandbox, the deagle is a script weapon and is on my left hand while left clicking shoots like a HL2 pistol, I can't see the knife, I can't arm the C4 or pick it up again because it's invisible after I drop it.

I also get all these error messages in console:
Unknown command: ttt_cl_startpopup

There are a lot of other errors like these. Can anyone help me with this? I have CSS installed and HL2EP2. Thanks.

A new traitor weapon I believe would be a great asset to the selection would be "Dummy". An unidentified body stays unidentified and can lure innocent terrorists and detectives to their death by the traitors waiting at hand to dispatch them, like a trap. What do you guys think?
