Hi everyone.... i had the same problem with the "transfers not allowed" and i think that the problem has to be with the soundcard. I use a mbox2 and i think the decoder for mp3s is not compatible with Sonicstage. To solve the problem i had to convert the mp3s to wave in winamp and then import them into sonicstage, then it worked. Take care and good luck! Peace /ONE-P.M
