I'm looking at the enbeffect.fx file and there is // in front of every single line. Also, I cannot find USE_LETTERBOX_EFFECT.
The installation video is in the nexus mod website. The creator of the mod saw it and told me everything was correct.

Hey guys! I love this mod but I was wondering if anybody could help me get rid of these things that appear on the top and bottom of my screen. It only started after I installed the mod and I did it all following the installation video.
