I’m frustrated

Java Network Programming early release problem.

Yesterday I bought the early release of the fourth edition the ebook "Java Network Programming" but, when I go to its download page, I can only download the third edition of the book, which it looks like being the one that I bought (but I didn't!). What's happening?
Thank you in advance

Edit: I've just checked my web browser's history and I noticed I have never visited the 3rd edition's page, so there's no way I could have put it in the cart.
