UI wont show

[lazerkatz]

Well ive done everything i could, i cant find antoher WOW folder or anything. at first i started followed the directions, renamed the WTF folders and all that jazz. but no matter what, my old UI would always show up. as i said i couldnt find another wow or anything that id have to delete. i do use curse client which i reinstalled (it had all my addons on it) and i uninstalled each and every one. then i installed the UI again replacing the folders, and renaming. i log on and its just the default UI theres no addons tab or anything so i can click load out of date addons or anything, theres just nothing there... what am i missing? is there some weird spot another wow could be? HELP ME i WANT LUI REALLY BAD!
