Restoring a FLAC3D sav state from a previous version

Hi FLAC3D Community,

I’m using FLAC3D V7 to restore an older version sav file that was created using FLAC3D V5, and I’m getting the following error:

Could you please advise how can I restore this file?

Many thanks!

Update - I manage to open the file using FLAC3D V5.0.
To Save your time in the future, “sav” files created using FLAC3D V5.0 will not open in FLAC3D V7.0
