Help I cannot fix this for my life!

Whenever I load up DarkRP I have all of the weapons saying “PRINT NAME”.
Here is the error:
Error creating ‘keys’ (Make sure the file is AddCSLuaFile’d and there aren’t any errors!)
Error creating ‘gmod_camera’ (Make sure the file is AddCSLuaFile’d and there aren’t any errors!)
Error creating ‘pocket’ (Make sure the file is AddCSLuaFile’d and there aren’t any errors!)
Error creating ‘weapon_keypadchecker’ (Make sure the file is AddCSLuaFile’d and there aren’t any errors!)
Error creating ‘door_ram’ (Make sure the file is AddCSLuaFile’d and there aren’t any errors!)
Error creating ‘arrest_stick’ (Make sure the file is AddCSLuaFile’d and there aren’t any errors!)
Error creating ‘unarrest_stick’ (Make sure the file is AddCSLuaFile’d and there aren’t any errors!)
Error creating ‘stunstick’ (Make sure the file is AddCSLuaFile’d and there aren’t any errors!)
Error creating ‘weaponchecker’ (Make sure the file is AddCSLuaFile’d and there aren’t any errors!)

Reinstall the base gamemode, sandbox, and DarkRP.

How would I go about replacing the base and sandbox I have already replaced DarkRP

Run a full server update with validate command.

I do not have the ability to do that is there any other way to fix this it is preventing anyone from playing on my server.

You should always be able to do that. If you do not know how, then contact your GSP.
