We are in the middle of an ebook conversion from a print layout (INDB and associated INDD and image files) to epub and mobi for a customer. We are in the part of our workflow where we export to ePub and then go back to InDesign to fix problems that remain. It has been exported to ePub dozens of times. Suddenly (about 5 days ago) InDesign started to crash every time we exported the file to ePub. Even if we go back and open an older version of the file. We replicated the problem on a PC also, so it happens on both Mac and PC (InDesign quits). We contacted Adobe and they got us to update to the latest version of CS6 but it hasn’t made any difference. Has anyone else had a problem like this? What can we do about it?
The file could have become corrupted. Try exporting as an IDML file and reopen in InDesign.
