I just tried — it works for me. I could be a temporary glitch: the site is under improvement, or have been recently. I would advise you to try again. Just in case, try downloading from other sites (see the comment by joshrduncan2012).
Anyway, if you can see any defects, you can report them here:

Good luck,
