Gmod Server PointShop Playermodel Error Sign

So Today I installed pointshop in my server.I successfully put the model destination in the lua file in the point shop playermodel,but when I restart my server and look at the playermodel at the shop I have a big error sign.How do I fix this?

You need to force the client to download the player model files.
Edit: It’s probably faster if you just watch this video and follow it.
