For those that don't know, a driver update for NVIDIA broke the SweetFX graphics mods to where every time you try to boot up 2K14, you get this error message:
There is an easy way to fix this without the need of rolling back your drivers. The first step is to locate the files "dxgi.dll" and "dxgi.fx"
Then rename two files to "dxgi.dll.bak" and dxgi.fx.bak"
If done correctly, the next time you run 2K14, the game will start without any error messages and the filters will be activated.
