Doesn't matter - the "new" bit torrent-based downloader does nothing (yes, my firewalls are configured properly). The old downloader works fine (albeit slowly).
And because it doesn't work for you there's no way it will work for anyone, right? I just downloaded it and it's up to 120 kb/s and climbing. You just have to have some basic patience and let it warm up. Bittorrent isn't html, it doesn't start immediately at full speed.
