This copy of iTunes is corrupted or is not installed correctly. Please reinstall iTunes. (-42037) on Macbook Pro OS X 10.10.4 after last update.
I can't open iTunes at all. It seems like this may be linked to Apple Music somehow?? What do I do here? All of the uninstall and reinstall directions I'm finding are older. Is my iTunes library saved somewhere or did I just lose all of my music?
