While I'm waiting to hear back from Amazon CS, I thought I'd see if you guys have any suggestions. So far all books have been fine on my Kindle (K2) except for one. This particular one which I purchased a week or so ago will not open. I've tried deleting it and re-downloading several times but to no avail. I get an error message saying it cannot open the book. So frustrating! Has anyone had this happen and do you know of a solution? Otherwise I'll wait to see what CS says. It's just a regular Amazon Kindle Edition book, nothing strange or unusual.
