Problem trying to update book with Producer
I found a typo in my book and I wanted to upload a corrected version. Everything works fine in iBooks Author, but then when it opens producer I noticed that the title is incomplete and has odd spacing. So I fixed that and made all entries and then when I hit submit I get an error message telling me the file can't be changed because it has been changed by another application. I have no idea what, if anything, I am doing wrong.
