I wish there was a way I could go into the file and fix the errors. At least, if I have the instructions, I can do it myself.

A Word document is giving the error: The file "***.docx cannot be opened because there are problems with the contents. When I click OK, I get, Word found unreadable content in ***.docx. Do you want to recover the contents of this document? If you trust the source of this document, click Yes. When I do so, it goes back to the first error. Murphy's Law - I have 5 backups of everything. However, unfortunately, this bad copy has been backed up on all! :-(

This one requires someone at a very high level of knowledge.

TIA.
