NPC reskin bug

I downloaded an NPC skin from garrysmod.org a few days ago.
I installed the skin correctly (I placed the Materials folder that I downloaded into the Materials folder in gmod/gmod, and placed models in Models Folder, again in gmod/gmod)

When spawned, the NPC texture is pink and black checkered squares.
I also get a message in console (Missing Material, or something like that)
Help?

Anyone?

Link to the pack

go to www.garrysmod.org I can’t remember the link but type alyx its one of those

The texture files may be corrupted,delete the files from the folder you copied it into and redownload the skin
