Saatanan's Hk weapon pack & Silenced gun pack V4

Hello FP.

Im having trouble with Both packs. The Silenced gun pack i installed but cant use the M24 and i dont have all the sweps like the pistols in there for some reason. And the Hk weapon pack ive tried so many methods of installing, i installed to addons. I took every folder and put it in its place (e.g. Models goes to models).

Could someone please help me!!!
