Cannot download updater

I am finding it impossible to download the updater installation file.  I can get the first 2.9Mb of it, and then the download comes to a standstill.  I’ve tried turning off my internet security, in case that was causing the problem- no change.  I’ve tried both Firefox and Exploder- no difference.  I’ve spent the last 5 hours fiddling with settings and am slowly going insane.  Is anyone else having this problem, and is it something on the three computers I’ve tried or something on SanDisk’s end?

I have the exact same problem. It starts downloading (fast) and then stops at 67%. Is there anyone who maybe mirrored the updater?
