Thanks this helped but not enough. I was trying to feed the I books author file directly. So, i went to File/publish and created a file labeled ITMSP. Then went back to the Publisher wizard. I was unable to load the ITMSP file but the Publication window in ITUNES Producer has the Ibook file I exported from IBA in it. I continued through the wizzard but chose not enter a target audience. When I got to the end and clicked on the button to send to Apple it went through a verification process and flagged the lack of target audience. So I went back and entered 13 and up. But the same error keeps occuring and I can not proceed. Any ideas on the following
1. How I clear the error message now that I have entered the right data
2.Is the Ibooks export the file that should show in the produce window, or should it be the ITMSP file that wont load there?
