Deathrun weapons not working correctly?

Okay so today I installed CAC (!cake anti-cheat) and it think it is somehow messing with my weapons addon because right after I installed it the weapons started giving errors when shot and they are completely invisible except for their shadow. I tried another weapons addon and got the exact same results. Can anyone maybe help me? Or recommend me to a working one?

Here are the errors im getting in console:

SWEP (ptp_weapon_base) is derived from non existant SWEP (weapon_base) - Expect errors!
