I'm having problems with sonicstage 4.3 crashing everytime I do a song transfer to my sony NW-003F walkman and then I have to restart the software. The songs do transfer but are immediately followed by an error message and crash. I just bought the Walkman with SS 4.0 and downloaded the update for 4.3. I probably need to reload the update but it took me 5 hours to do it the first time because of slow download speeds from the Sony server even though I have a fiber optic link to the internet.
