World of Warcraft add-ons?

Rename the add-ons file by adding a ".old" to the end of it, start WoW up, log in, then exit game, go back to the interface and there should be a new file that is named "Add-ons, put the addons you want into that folder, if that doesnt work, check to make sure it is the raw addon and not a folder in a folder with the raw addons, it confuses WoW sometimes.
