Hi, I bought a copy of Garry Whitta’s Abomination on ebook, and after the transaction completed I don’t seem to be able to get a download link again.  I didn’t get an email about it, and when I look at my "bookshelf" I seem to only have access to a browser version.  Fortunately I halfway saw this coming and made sure to download the mobi version before closing that tab, but the ability to ever download again is apparently lost to me.  I seem to have narrowly avoided a bad situation, but others may not be so lucky.  Is this working as intended?
