I am trying to make a flip book out of an 88 page PDF which has artwork on the inside front and back covers. 3D FlipBook is adding a blank page to the inside front cover, and then leaving out pages 87 and 88 from the end of the book. I am currently using the Lite version, but am happy to purchase the plug in if the Pro version solves this problem. Could you please help me to fix this? Thank you.
