Address table acting weird – breaking up, going from 14 pages to just 4 pages, changing text placement such as doc title, adding blank pages, etc.

I've tried just about everything that I could think of: shutting down and reopening, transferring to another new word doc, getting online and finding others with similar problems - but I could NOT FIND ANY CLEAR, DEFINITE SOLUTIONS...

Since I've essentially lost this table - just 4 pages left - I'm having to start over with saved backup copy that does not have all the many changes/additions I've made in the interim.

Has anyone on this Forum had any similar experiences with GONE-WACKY tables?

Is there a way to retrieve the last, or further back, saved copies - I do make a practice of frequently saving my work as I'm going along (Ctl+S)?

Thank you for any help you can give me!
