HELP! Evolve won't stop spamming one error!

[ThatRaichu]

This error in my evolve wont stop spamming my gmod. i had this before.

Can anyone tell me how to fix this god for saken error it even spams into my console, and whenever I open up my console it stops, but when I go back to game, i see it still spamming.

Hook 'HUDPaint' in plugin 'Player Names' failed with error:
[ev_plugins\sh_playernames.lua:53] attempt to call method 'EV_HasPrivilege' (a nil value)

Help please...

I'm assuming the player isn't valid.

I forgot to mention

It even does it when I remove evolve, and if I try to reinstall Garrysmod.
