My quick test must have been flawed. You can add a simple white rectangle on the page to force the conversion to PDF, or you can long press the song, tap the three dots at the top right, select "Print", and then use a "Print to PDF" option (assuming you have something set up on your device to handle that).

As far as the error message, there must be some kind of corrupted data in the song. Can you please long press that song, tap Share->Export as .msf and email the .msf to mike@zubersoft.com? I'll try importing it and see if I get the same error while exporting.

Thanks,
Mike
