The download is there, but Amazon makes it nearly impossible to find. The only way I've been able to find mine is by using the link provided in the original email from Amazon that I received immediately after ordering. I have found no way to locate it through searches on the Amazon website.
The following link brings me to my downloads on Amazon, it might work for you:
