Hi you all, i'll be short, promise! In my possession is a sony nw-hd1, a modded one, that plays mp3-files. I recall that the model only could play attrac-files. So i received a software that i could use, and was told that only this software and version worked. I've been searching for sonicstage version 3.1 from time to time now since 2007, without any success! Can someone tell me where to find it? Thank you thank you thank you!
