I've downloaded oQueue and extracted it into the right folders, yet I dont see any addon button ingame nor can I do /oq

When you are on your character selection screen. You will see the addons button on the bottom left hand corner of the screen. Click the addons button. If oQueue is listed in the list of addons, you have oQueue in the right folder. If you do not see oQueue in the list of addons, you have not placed it in the correct folder.
