Can't open file, saying it is Version 1.0

I am currently using Cubase 13 pro, and while saving a file last week, it got hung up and crashed. Now when I try and open the file it says it can’t open it because it was made with Cubase version 1.0. The latest backup file for some reason was days younger and if you look at the attached screen shot notice how out of order the back up files are.. they go in reverse by date.

But my main questions is this: is there any way to recover this file or do I just lose all the work I put in between 3/9 and 3/11?

Hi,

That means, the project becomes corrupted.

You can try to load it without 3rd party plug-ins, you can try on other machine.

If you have no other backup and the above will not work, I’m afraid, you lose your work.
