It's a known problem and I understand has been known for over a month but you CANNOT download "casual" games from Amazon.com. There's a technical bug in the download!
I either got an error that the downloader was offline (it wasn't) or it would download the mess into a .tmp file and then stick at 0% downloaded!
I called and found it was known. My complaint is, if it's known, and there isn't supposed to be any refund on downloads, why do they even ALLOW the purchase in that case?
I did get a refund but I was still not happy. I wanted the old Sandlot game, "Glyph". I have "Glyph 2" and "Kuros" but not the original since Sandlot sold out to Digital Chocolate and then Digital Chocolate abandoned all these games.
After the mess, the order disappeared from my games library after I got the refund. The only other any-where-near-reliable place to find the game was Shockwave (same price) so I did eventually get the game.
If you see a casual game (free games and other types are supposedly safe) that you want, CALL first to see if the bug has been fixed.
