Thank you for your response. I can guess that. However, I would like to know why the file during operation (almost two days, 10 hours each) as if reset to the state from two days ago. Despite autosave, manual saving. Moreover, why duplicates of this file (four files saved as separate copies to disk every few hours), they now look as if they were recorded in the state from two days ago, despite the difference of several hours, they do not differ from each other. Each time the file was closed. I am not a novice, I have been working as a freelance dtp for 25 years, and work with Publisher almost from the beginning. This is the first time this happened to me. Will I get any suggestions for the reasons?
