I use Firefox and have had no problems DLing 2 of the 4 kits (haven't tried the other 2 yet). I DL one at a time. Previously, if I've had a corrupt file or something, I have to clear it from my DL history, then delete it off my computer (including the recycle bin) or else it will keep DLing corruptly.
Thanks Robin, for all you do to make SSD so awesome!
