Yes, I did. Also replaced the startup.arc with the one linked by Curilang.
I actually had problems where when I tried to run the game with everything in the repack. I replaced the old files/folders on my a3 drive and overwrote them with the ones in the repack, and that was when it started throwing that "check to see if arkmdxp4l.dll and permissions are fine." and I couldn't even GET to the checking screen. I tried using my old arkmdxp4l.ll file and then It would go to the checking screen but would crash immediately after it said "eamusement... ok"
