If you open Indesign and then browse to and open the file rather than clicking the file itself will it open or do you get an error?
Let us know
The first thing you may wish to try is to rebuild the prefs files.
Just look in the [user name]/Library/Preferences/Adobe InDesign/Version folder and rename the SavedData file and the InDesign Defaults file to SavedData file.old and InDesign Default.old then reopen the software and try again.
Let me know what happened.
did yu transfer these files to this mchine or did you upgrade your software?
Let me know
If your files were created or modified in a newer version of the software then that would prompt this issue, So as a test you could download and try a demo of the new version and see if it works to open these files.
Let me know what happens.Thanks
Let me know how it works out.
