A time ago i downloaded a replacement pack for the HL2 weapons in Garry's mod then i didn't want it anymore so i checked the files that came in the pack, deleted them from my Garry's mod and now the smg1 is invisible in first-person cause i don't have the view model (v_model) and the other weapons doesn't Have world models (w_models) so i cant see the other weapons in third person. Its only the RPG and crossbow and the 357, that didn't get replaced so they work fine. But the replacement replaced the v_models and w_models so if i restore the models from the trashcan i don't get the normal HL2 weapons but the replacement pack so i wondered if anyone could help me 
(P.S because i don't have the w_models and v_models i freeze when trying to join an online server)
