Okay so I waited to hear back from Amazon. Since they are so far silent on my situation. I got the right file up now and everything seems fine, so I figured out my own solution.
Starting today (4/30/15) and ending Saturday(5/2/15) Elemental will be free. You can "buy" the book by clicking on the title or the picture.
So anyone who bought Elemental during the sale and received the wrong file can grab a copy. Also people who were not sure if they would like the book can now grab it for free just in case they might.
Again I want to apologize for anyone inconvenienced by the mix up. I hope anyone who gets the book enjoys it.
As always, have fun, and keep writing, and reading.
EDIT: I got an email saying that anyone who bought Elemental should get a notice to update to the current file, so that is good.
