Error opening an older file

[Generator]

Hello,

 

I went back to an older character I haven't played in a while.  Her Mids file is from about a year and a half ago.  When I go to open it, I get the following error.  Any idea what's wrong, or if there's any way to set this right?

 

Thanks,

Generator

 

EDIT TO ADD: last night I realized if you open an mxd file in Notepad, you can read it.  I'd like to know if the issue is fixable, but the workaround works! 😁
