Format error in the file sub-document content.xml

[spudman]

I am at wits end trying to open my financial spreadsheet with the above error message with ver 4.1.2 on windows 10.
It says "Format error discovered in the file sub-document content.xml at 2,625040 (row,col)."
My last backup won;t work either and don't know how to fix this without going back to a older backup and input everything from last december. I am exhausted reading similar problems from several years ago which I can't figure out what they are talking about. Can someone please help me recover this file.--Spudman
