Indesign update now not opening older Indesign files
When trying to open older version Indesign files I am now getting the following message:
Adobe InDesign may not support the file format, a plugin that supports the file format may be missing. or the file may be open in another application.
Can anyone shed some light on why this is now an issue. All that has changed is we've just updated Indesign to version 15.1.4. Yesterday prior to the update, all older files were opening fine?
