Vehicle Errors (Lua Error)

Hey I was hoping I could get some help for this

[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:110**

I just now started to get errors from it when I got LW vehicles And no other vehicles do this.

FIXED!! I forgot I had the VU-Mod installed with this and It messed up everything
