The autoupdater is effectively a torrent client with a built in torrent, even if you cancel it and restart it later, you wont lose your progress.
So what should we do then?
Pause download and wait for hotfix.... Might not come for a while.
Play another game to quench your boredom in the meantime.
Also maybe you should exit the AutoUpdater, as I believe it continues to seed files as long as it is running, and there is no need to seed a broken download right now.
