George, I did it using the same thing I sent you (different code, though) and it worked fine - be sure you're putting in that exact number with the five zeroes. Otherwise I can send you another code. Or were you able to get to the download part and then it didn't work. I got it into iBooks on my iPad just fine.
I copied the code directly, so I wouldn't make a mistake in retyping the code. Otherwise, I was able to download it onto my Kindle with no problem. That process worked, but when I opened it up, I got the title at the top of the screen, and the progress bar at the bottom saying I was at 5%, and the rest of the screen where the text should be was completely blank. I couldn't page forward or back. After about 10 seconds or so, it would kick me out to my list of book titles with this error message:
The selected item could not be opened. If you purchased this item from Amazon, delete the item and redownload it from Archived Items available in Home. (close)
I would click on the "close" button, the message would go away, and that would be it. I tried deleting the file and I redownloaded it, but it did the same thing. I am just about to send a message to them in their "Contact Us" page with the same information.
