TTT Gamemode not working on dedicated server

I have a dedicated server, running the TTT gamemode. When I load it up, the GUI is fine- But I can’t switch weapons, and the only weapon I have is a physgun that’s detached from my body, and floating in the middle of the map. The server console is throwing out shitloads of missing content errors, but I correctly installed the CS:S content. Help?

You can see the proble firsthand on the server:
