Hudpaint Error

Well when ever i go on gmod and spawn in a map i got a full screen of these errors:

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

I have no idea what they are and how to fix them so please people, help me. I cant open my Q menu or cant use my tools or weapons, so that pretty much means i cant build anything. So if anyone can help please do, thanks.
