Can't Retrieve melody line from Saved to disk

I archived a song last year to hard disk and when I retrieved it, everything was there save for the melody line. The lyrics were saved in their file, but nothing on the score.
Could it be due to updates that the file is not being read?

Hi @missycarter, can you email the file to We will recover it send back a working file and hopefully fix whatever bug is causing this. Thank you!

Hi @missycarter, can you recall if this project was originally created with Hookpad 1 (the old Flash Hookpad?)

We had another user report that when loading songs with multiple melody voices originally created with Hookpad 1, it is possible to have one of the melody lines get screwed up in the import.
