So in short how I did it, I downloaded the unren program (you can find it by just searching "unren" in your browser) then I dragged it into the folder where the game is located, unzipped it and ran it. I selected the 1. and ran it, then the second. After that i searched within the map with the search tool to find the "scenes" folder, and then looked for "sabiabargropeA (1)" image, and it was marked as a .png file when it should be .jpg; so i renamed the .png into .jpg and did so with all other bar grope scenes, of course my computer asked me if i'm certain if i wanted to change the name and i chose yes. I think this should help you with this problem.
