Spotify would not open, so I tried to re-install the app on PC. Would not install because I already had the app. Tried to un-install, but was not showing up in my control panel/programs list. So tried to uninstall from start menu. That wouldn't work. So I tried deleting every file i had that was spotify, manually. Well I guess I didn't get them all, because when I try to install again it still says I have the app installed. I am paying for premium and would like to get my app working again.
