Then follow the instructions listed:
1. Locate C:\World of Warcraft\Interface\AddOns\nUI\Main\nUI.lua
2. CREATE A BACKUP OF THIS FILE AND SAVE IT SOMEWHERE SAFE
3.Open the file (I prefer opening and coding with notepad++) and CTRL+F for "Worldframe"
4.Comment out every line you see with Worldframe(should be about 3-4 if I remember right)
5.Commenting out a line can be done by adding "--" infront of the line. Or "//" (Personal preference, I like -- because it looks cleaner when I code LUA)
6. Then simply save it.
If you have any questions or issues, feel free to PM me or post on this topic.
