I have tried doing as suggested but I started with 2010, then 2013 then 2016 and finally 2019.  I own all of these licenses so I thought I would go there first.  I was able to install all of the software on my Windows 10 platform but when it comes to restoring the file, I am unable in ANY version.  It allows me to open the file but then I have to update it to the latest version so I hit YES and it runs for a long time and finally stops and I get the message that my file was NOT restored.

I have also tried File Doctor but it tells me the password is incorrect.  There is only 1 password for the file and of course I tried a few times to be sure I was entering it correctly.
