Sounds like the same bug that caused us to release 8.11 and 8.12. Start the application in a terminal window and paste all the output here.

Are these errors from starting with the original .ardour file or with the one you’ve been manually editing?
Because the errors seem a bit weird : “file is too short, it cannot be a MIDI file” and “Found a sound file that cannot be used by Ardour”

You’re apparently using Ardour 6.9, so the problem isn’t the audio region issue that people running 8.x have been bit by.

Thank you for answering Peder.
Actually after reading some comments on some sites about similar problem i changed two referans number showed in error message decenting by 1. All my updating is that. The file is original Ardour file , 73KB . I can send the file if you ask.
By the way i faced this problem first time , i dont know what happened. I use this session
file in all my projects . When i’ve done i export the midi as audio , use it in a video , and my job is done , next time with new project i open same session and delete old midi record and recreate new one . Maybe its a weird way but im very new with Ardour and i dont need the old session records.
And i searched the MIDI file in directories , found related MIDI file , i would import it and export as audio but file was empty and backup file was empty too

“Found a sound file that cannot be used by Ardour” suggests to me that the session doesn’t just contain MIDI data.

A cleaner workflow in your case would be to have a backup copy of the session file and copying it to the active session file when you’re using it, rather than opening the same file over and over and removing the data from the last session.
Or creating a template from the working session file.

Paul, or at least someone more skilled than me in dissecting .ardour files, should probably have a look at your file. Preferably the one that originally had issues; before you started editing it.
