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:

 ![image](https://canada1.discourse-cdn.com/flex031/uploads/itasca/original/2X/d/d91118d67aa65c92525c1c7dfaab5d2b35df6b90.png)

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** _
