Need help with a shader error. It shows in red and wont work.

I get this trying to make it work in Darksiders 2.
I'm new to these types of problems, i don't know how to fix this if it can even be fixed.
I want to enable NiceGuy Lighting effect, since it adds amazing global illumination in other games, like Arkham Knight and Dragon Quest Builders 2.
warning X3571: pow(f, e) will not work for negative f, use abs(f) or conditionally handle negative values if you expect them

That effect simply isn't supported on D3D9 right now (which this game is using) and will either need to be adjusted by its author or you have to use DXVK to wrap the game to Vulkan, so that ReShade runs with Vulkan instead.
