Hi there - I am also having a problem with the library in the WAV conversion tool being empty, and the previous posts don't solve it, alas. Choosing "all convertible tracks" on the display mode does not display any files. An online-tutorial indicated that I should also be able to choose "Recorded on HiMD" (or something like that - I can't remember exactly) from the display mode, but that doesn't appear. The recordings I am attempting to convert were recorded live on an MZ-NH1 through the Mic input, so they should be convertible, yes? They were originally transferred from the MZ-NH1 to SonicStage 2.0. Then I upgraded to SonicStage 2.3 (the files transferred to the 2.3 version okay, as far as I can tell). Then I downloaded the WAV conversion tool, but it isn't picking up the files from the SonicStage library. Can anyone help? I want to burn these files to CD but it has been an incredibly frustrating trip!! Reading the posts here has been extremely helpful - thanks so much for all the info. I was so glad to find out I wasn't the only one cursing Sony.
