ok, so i have tried to install two addons. I have put them in the right place (program files/world of warcraft/interface/addons) by extracting the downloaded files to this location but when i close down my game and open it up again, there is no addons button on the character selection screen.

Any help on this would be greatly appreciated.

Many thanks

First check that each addon have its own folder. So that each addon is represented by a folder(s).

If the "addon" button isn't apearing, its usually wrongly installed, or not at the right place.

*edit* (not sure if thats the deal, but usually you should allways install addons whitout the game running)
