I think it is unlikely that you will delete it. (But it is not good if you copy the folder in the wrong direction.)
Is the music folder you have open the same as before? Please check it.
Viewing post in New version deleted all the songs I was working on?
Version 1.0.3 gives me an error on launch:
pyxel error: failed to initialize SDL Audio: WASAPI can't initialize audio client: The handle is invalid.
in 'Audio'
Any idea how to fix this? I see another post with a reference to 'use the shortcut' however in the zip file I downloaded there is no shortcut to use ^^.
