Which error? Unknown error? If so, Kim has hairstyles in the script that are not in your wz files.
Being long time ago, but I believe you change this in World.properties under 'MTS' I believe it was something like 'MTS brings you to FM' false or true. Its however possible the MapleStory emulator you use doesn't have this function, since it comes from Odin.
Can be due to many reasons, which most public emulators have issues with. Unfortunately this is not something I can blindly (and even if you tell the emulator you use) can point a fix for

Fairly sure the damage hack cap change in this tutorial works, but once again been long ago I last touched this.
