Awesome! Thank you. This sure beats the retarded compressed & split archive nonsense they came up with that no one on the planet can figure out.

Too bad it was hyped so much, otherwise it wouldn't have been so popular and could be able to be downloaded much easier :/

Download is taking forever. Must be too many people downloading at once, may have to try later since this is the only download that appears to be working. Takes 10 minutes for 10 MB

If you're having trouble downloading it from here, go to shacknews. Much less traffic.
And yes, it is an official download mirror.
I am currently downloading at 250-300 kb/s
