Problems producing KDP book from FrameMaker 2020 on KDP
I have a book which successfully published with FrameMaker 2019. I copied the folder with the book and accomopanying files to a new directory and upgraded everything to FrameMaker 2020. The PDF produced by this causes the dreaded KDP message of "There are errors in your file" message with no further diagnostics. (I'm using a 64 bit Windows version of FrameMaker version 16.0.4.1062) Many thanks for any insights!
