Level editor sdl.dll problem

[xxtimetokillxx]

Been trying to install the level editor for Amnesia. I have the steam version, so I followed the directions on the wiki to place them in the correct folder, C:\Program Files\Steam\steamapps\common\amnesia the dark descent\. Once placed there, I got the "sdl.dll missing" error. I've searched everything there is about the error and I can't seem to find a fix in my situation. I've tried putting the files in different locations, reinstalling them. I downloaded a program that supposedly would fix my sdl.dll problem, but after scanning, I had to pay for it to fix it.

Does anyone know what my issue is?
