Hi, I have the mp3 player NW-A1000, but i lost the CD of Connect Player that goes with it. So I downloaded Sonicstage 4.3 on my laptop that is supplied with windows vista. It looks like Sonicstage runs ok if I'm just playing music on my laptop for example. But everytime I plug my mp3 player, the message "Sonicstage has stopped playing" appear. Would you maybe have a solution I could try to solve this problem ? Many thanks Glasgow
