Major DarkRP problem

OK so I’ve reinstalled DarkRP numerous times because of this problem, all the DarkRP utilities are missing like: Keys,pocket,stun stick, camera, etc. Also all the tools are missing in the Q menu, please tell me whats wrong

Here is the code i get in console:

Reinstall DarkRP, base, and sandbox. You deleted default files.
