After running all night with no issues, I am able to conclude the issue with the missing One line weather file, was due to ACP being configured to save images to the USB external Hard drive.
Once this was changed to the C: drive, there were no further issues. I don’t quite see the connection between the one line file and the USB external drive, but I am just happy its operational once again.
Bob, Thank you for your support !!
