Problem with ePub file
Hi, i've made an ePub of my book but i've send a first version in .ibooks. Now where i try to update version and change file from .ibooks to .ePub, iTunes Producer show this error:
ERROR ITMS-4096: "mybook.epub: the publication is expecting a multi-touch asset. You cannot upload an epub to this publication." at book.
Anyone can help me?
