Corrupt xml in .ods

Hi

I’m using LibreOffice Version: 5.0.3.2 on ubuntu.

I have a file that I saved with a password and been using for the last couple months. Now it is all corrupt and so are the visions from months pass. It is saved on s server that we keep monthly backups for.

I have opens it as a zip file and all the xml are corrupt is there any way to recover this file or would I be better off just starting again?

Thanks for any input.
