Console Error Problem

This only seems to happen for me, but this is spamming my console after a fresh re-install:

ERROR: GAMEMODE:‘HUDPaint’ “Failed: sandbox/gamemode/cl_init.lua:74: attempt to call method ‘PaintNotes’ (a nil value)”

Anyone know how to fix this? I don’t really have any addons installed that aren’t the normal ones. (PHX/wire/etc)

Yeah, I got this after a fresh install.
I’ll upload my sandbox game mode folder in a zipped folder to somewhere like megaupload.

Edit: Also verify files and defragment game files. I’m not sure which fixed my problem, so just do all 3.

It’s a fresh install, and defragging/verifying stuff has nothing to do with this problem.
