When saving Song my registration get erased

[m31asy]

When i save a song, my complete registraion get erased and cant reload the song, because he cant find him.
And yes, i ve already found where i saved, but i looks like he only saves he style, not the complete registration, even i told him to save all.

Thank you

PS: i found out you need the style in the same directory as the sty2 file, but the registration dont get reloaded.
