@svante, yes, the file in question does reside on the local drive and I haven’t experienced any crashes or reboots other than a reboot that I performed in hopes that it might fix the issue.
It’s possible that the file may have been open during the install of the new version and I closed the file, that may be what caused the issue with the file.
@Josh, the file is a plain text file. I don’t run Windows backup but I do backup the file, just not as regular as I should, this will teach me!
I posted here in hopes that it might be something that has happened to others and that there might be a fix but it looks like it’s an isolated case.
