Can't fix errors

I get two different errors when I go on this server:

  • The big red “ERRROR” text for Riot Shield and H&K MP7
  • Errors in console. Every time I’m loading up the server, it keeps trying to attempt files.

This also from the mp7:

And it keeps repeating every time someone shoots the gun, obviously.

Can anybody please help me with this? Yes, I do have CS:Source, I also tried verifying it too, and it is. I can use all the other CS Source weapons. Nobody else is getting errors but me. I’ve tried re-entering the server few times and restarting garry’s mod too.
