First step is to always disable all of your mods. I assume you're using 7H 2.0. Click the drop down arrow next to the Play button in the menu and choose to play without mods. If it runs fine, then most likely a mod is creating an issue. If it's still broken, most likely something bad happened during your process of installing Remako (which is not necessary to do--Remako options are included in all of the Qhimm catalog mods which are available directly via the Browse Catalog tab)
On a side note, IMHO Remako doesn't hold a candle to the newer Satsuki's upscales and retextures anyway (also an option in all of the Qhimm catalog mods) and I recommend using those.
