I have an InDesign document (over 150 pages, over 400 "stories") that was packaged and exported to InCopy and sent to an editor. The editor made corrections and sent it back to me. I opened the document in InDesign and about half way through accepting and declining changes, it "unexpectedly quit" and now will not open or recover. Any suggestions as to how to recover this document. I have shut down, restarted, tried a different computer with InDesign. No luck!
Ideally InDesign should have auto recovered the file, unfortunately not in your case. I would suggest you to check once with the Design team over phone and see if they can recover your file Contact Customer Care
