For those that want it (for the Blizzard's Test Realm only right now), here's the cracked downloader for the 1.4.0 patch:
It is the same exact thing as my last release except it downloads the newer patch.
So if you are one of the many thousands who suffer from slow or non-existant downloading while using Blizzard's downloader, you'll want to try this. It has all of Blizzard's features unlocked for direct download and what not.
Once again, I hope this helps!
