Flac 7.0 prj file in Flac 9.0

Hello Itascans, I am trying to open the Flac 7.0 project file in Flac 9.0 but it is not opening. I want to confirm, is it impossible to open the 7.0 project file on 9.0?

Is the file from FLAC2D or 3D?

It is from FLAC 2D. I think that could be the issue.

Yes, you cannot open the old FLAC7.0 file in FLAC2D 9.0
