First of all, we highly recommend posting support issues either on the Requiem website or the Requiem forum thread, so that a team member is guaranteed to see your post. 
Edit: Nevermind, I see you did post in the forum thread lol.
Second, your problem should be resolved by going into the mod's pipeline effects folder and deleting these files.
