Kindle Fire HD 2013

First of all i would like to thank the developer of this wonderful piece of software. it's great

now the problem i am having ... i just brought the new Kindle HD about a month ago ... i have a very large extensive book collection ... and i have successfully converted e-books to MOBI and was able to e-mail them to my Kindle

for the life of me i am unable to have the books appear in the books section of the Kindle... they keep popping up in the documents section of the Kindle

i have followed to the T all the procedures that have been posted to get the books to show up on the books section and to my dismay they continue to show up as personal documents

a happy note is that i was finally able to figure out why did the book covers show up with a big PDF type of cover ...the trick was that i needed to up load bigger picture covers .for them to at least show up in the carousal with an original cover
