I had exactly all the same issues as you. Tryin to connect to coop campaign with a friend. We tried the launcher fix and it made all our games from the cnc collection on origin not playable. So had to uninstall them all and reinstall. Still connection issues is out of our hands so hopefully the guys get a fix for that soon. Only other problem i have now is cnc 4 wont load anymore ive uninstalled it reinstalled and nothing. It was working earlier because we were guna try coop campaign on that so seems the launcher fixer has messed things up big time so keep away from it
