What happened with me is I dowloaded a bunch of add ons, took a break from wow, and when i came back they were out of date. Clicking on the load out of date add on button is not working and I have completely deleted my interface folder and they are still there. Also, when i dowload new add ons and go through the whole process, the new add on does not appear when i click that little add on button in the log in screen. HELP ME
