Using Near Infinity to make items

Ages ago, I did extensive modding for Baldur's Gate II using the old Team BG tools. Never released them, just made them for personal use. Lost them when my old computer crashed. I don't want to really get back into modding, but there are some of my old items I'd like to remake. However, I can't get DLTCEP or any other old program to work. I've tried using Near Infinity to make an item, but I can't seem to figure it out. Any tips?
