Okay, so I was in a place without internet for a long while, and I don't know if the old version is even supported anymore. But here we go.
I downloaded a preset from thelazy.net and went through the process to apply it to a game -- in this case, Borderlands: The Pre-Sequel. Loading the effect failed, and now I can't get rid of it. I've uninstalled the game, I've uninstalled ReShade, I've tried overriding it with the latest version of ReShade, but I have no idea what I'm doing there and mess that up every time. I'd love to able to use the preset I've downloaded, but honestly I'd settle for someone telling me how I can just get my game back to normal.
