I'm having Win XP SP2 and kaspersky internet security(7.0) I'm running Sonicstage 4.3(the latest) and own a NW-E015f. Every time i transfer songs to the device, I either get a blue screen during the transfer or after it. So i can hardly transfer any songs to my player. It's really frustrating.There is no driver mentioned on the screen, just an error code and it's different every time. I'm able to transfer with ML_Sony using winamp but i want to use sonicstage. Any suggestions?
