FINALLY!!!! It would have been more cost effective for me to just re-purchase the book since it cost so little but I refused to do so. I also refused to do a complete shut down and re-registration of my account. Last time I did that it screwed up everything.
Would it even have let you re-buy the same book? On amazon it tells you when you have already purchased the e-book. And i don't think it will let you buy it again.
You can buy as many copies on Amazon as you want to. Not sure about Kindle, but I know that's true of regular books, even when it says you've already purchased it.
