Install the KindleUnpack plugin. That will allow you to shift the files from the AZW3 to ePub. Then use epubcheck to check the ePub and fix any errors that are found. Then you have an ePub you can use as you want.
Sorry, but I don't have a clue. I'm using a plug-in to convert. Is this KindleUnpack a different plug-in?
I don't know what epubcheck is, but if I have to spend time checking and correcting a conversion, the benefit of buying from Amazon at a sale price is lost, and I'll stick to purchasing epubs and avoid the hassle.
