each time i log in the addon tab wont show up. plz help.

i have my addon unzipped and i don't have double folders.

Then you have the wrong location. Read the sticky at the top, or find one of Camealion's posts and read the links in his sig.

As said above, you probably dont have them in the right place. Make sure they are in the right folder, then log into the game and click on the Addons button at the Character Log In screen. Make sure you check "Load Out Of Date Addons".
