When I open an .ai file, it displays this message and then opens without all my graphics? How do I get my complete art back? What does this message mean?
the message means something went wrong the last time it was saved.
Try this create a new document then go file place and place the file in the new empty document. then resav that if successful.
Or behind door number two try to open it in Acrobat.
