After converting all my mp3 files to ATRAC3+ (24 hours for 3000 tracks!!!!) the sonicstage library recognises 2 files for each track, one MP3 and the other ATRAC3+. This is fine. However, I cannot find a way of tyransfering the ATRAC3+ file. Sonicstage will only still transfer the MP3 version. Please can anyone help me with this useless piece of software!!
