I haven't tried to mess with the config stuff yet but wanted to let you know that it's preferable to use note pad or any type of note pad editor instead of word pad.
If your are using word pad I believe you need to save the file as unicode instead of word text and don't use word wrap,also when you add code to your note pad it's best to leave one blank space on each code line.
Sometimes but not always not leaving one blank space will break the code or the game client can't detect the code or something.
My prefer editor is using note++.
