The Arma3Sync repository has undergone a significant upgrade.   The upgrade is designed to deliver faster performance, more reliable connections, partial file transfer and more!   As such the URL has had to change for the repo.  Please ensure you remove the old ATC repository from ArmA3Sync before adding the new one.   Please add the new repository using the following autoconfig link:  http://www.anztac-servers.com/repo/.a3s/autoconfig
