Toolgun gone

I’ve been looking everywhere for a fix to this, but if I choose the tool gun all I get is a pistol. I really can’t re-download GMod due to an internet cap, so it would awesome if someone could help fix this!

Console output that looks importantish if it’s needed -

[AddCSLuaFile] Couldn't find 'shared.lua' (@gamemodes/sandbox/entities/weapons/gmod_tool/init.lua (line 2))
Couldn't include file 'shared.lua' (File not found) (@gamemodes/sandbox/entities/weapons/gmod_tool/init.lua (line 9))
Couldn't include file 'includes\modules\glon.lua' (File not found) (<nowhere>)

And a screenshot -

A simple Verify Integrity Of Game Cache should fix this.

I just tried this twice, yet there’s still no tool gun.

Get rid of your addons.
