SWEP's knives textures/skins don't load

So, I have a Garry's Mod Deathrun server, with Pointshop 2, and I downloaded the CSGO Knives SWEP's addon, I put it in the addon folder, and then I restarted my server.
After joining the server, I saw the knives, but when I equipped them, they were normal vanilla skins, in Pointshop 2 the textures / skins were there, and when I dropped them on the floor too, not only I had this bug, also the people who played on my server.
I hope someone can help me!
Thank you.
