1.0 Release 5
The updater is now sentient can update itself now, so you shouldn't need to ever download anything manually again, not even launcher updates. This update can be applied via the existing version of the updater. Going forward, you should avoid running the updater manually, and instead always run it through the Advanced > Updates tab, as this is the only way to update the updater itself.
However, attached is a fresh copy of the whole thing just in case an update broke your updater at any point.
