Error 13014--can't open iTunes
I'm on an early 2011 Macbook Pro with El Capitan 10.11.1 and have searched high and low for why I can't open iTunes. My hard drive is not full and my iTunes content is stored on a Seagate external drive (never been an issue in the past). I can't uninstall it since it's required for my Mac & reinstalling over a current version won't do much anyway. My iTunes version is 12.3.1. I've tried renaming the Genius files (worked on previous versions) and can't find a solution.
