Vehicle "Viewmode" Errors

Whenever I get in a vehicle in my server it says that:

[ERROR] lua/autorun/client/clientvehiclescript.lua:14: attempt to index global ‘gmod_vehicle_viewmode’ (a nil value)

  1. fn - lua/autorun/client/clientvehiclescript.lua:14
  2. unknown - addons/ulib/lua/ulib/shared/hook.lua:179

And I don’t understand why, It never happened before and I didn’t add or subtract anything from the server, so I’m confused as hell, and very pissed off that this bug just randomly occurred.
Any Fixes to this problem?
I checked the file location and there isn’t a clientvehiclescript.lua from what iv found it was removed in Gmod 13.
I have TDMcars Installed.

Nvm Got it it was the automatic mounting of addon when you have fast DL setup so it was installing a buggy addon I got rid of along time ago
