i need help

[Mr.Dr.DuD]

can anyone tell me why when i try to get on a server a thing saying
pure server:file[game]\pak1_011.vpk does not match server file, and kicks me out of game

We force file consistency so your skins are being rejected by the server. Try deleting whatever skins you installed.

Mind sending me the skin you were using?

Wait, we can't use skins? D:
