I can't get rid of this error.

My hard drive got wiped a few days ago and I’ve had to reinstall GMod and all my games, so I installed my addons as well and since I’ve done that I’ve been getting this error in my console and its taking my FPS away so badly.
[ERROR] lua/autorun/sprint_lang_system.lua:58: bad argument #2 to ‘SetTexture’ (ITexture expected, got nil)

  1. SetTexture - [C]:-1
  2. ChangeTextures - lua/autorun/sprint_lang_system.lua:58
    3. fn - lua/autorun/sprint_lang_system.lua:74

If you could tell me how to fix this, it would be much appreciated

Delete that file and the error should be gone.
