Custom shaders mod causing Assetto Corsa to crash on startup

I bought Assetto on steam, donwloaded content manager, installed custom shaders patch (version 0.1.60). Error message is as follows

Unexpected error
Failed operation: `load(device,chunk)`, error: 0x80070057, invalid call

File: source/settings/custom_textures.cpp
Function: init

After pressing ok, the results screen say:
Game Crashed
Error might have something to do with

AC\game.cpp (23): Game::Game
AC\acs.cpp (450): wWinMain
f:\dd\vctools\crt\crtw32\dllstuff\crtexe.c (618): __tmainCRTStartup
Disabling/Uninstalling Custom Shaders Patch stops the error from ocurring, but i still want to be able to use it, since it has many CPU/GPU optimisation settings
