As stated... The main things to watch for are that the docs are horrible.. There is little to no instruction on how to create the config files properly. That is what messes up most people. Read the threads and most of your questions will be answered.

If you come up with another problem during install you can post and someone should be able to help you.

Too many possibilities to cover in your case especially since you are doing edits to already modded files.

Many times the expected code is no longer present in a file that has already be edited by other mods. This could make it difficult to know what should be changed.
