Its in my addon list, but it says out of date since the patch. Same as my Iron Leather skin. Others say these are working fine for them but they dont wanna for me for some reason.
They worked fine before the patch. I did a search for it and there is only one on my computer. Same for my wow.exe. When I type /nui gui in the game it says its not a valid command.
*edit* This is my path: C:\Program Files\World of Warcraft\Interface\AddOns. Yes I run Vista.
