SVL

Hi all, I am new here, and I hope I will be able to contribute to this forum sometime in the future, but I guess I only have questions for a start;) Are there any benefits in upgrading from Sonic Stage 3.1 to 3.3 if I would only use the app to transfer music from my PC to NW-HD5? SS 3.3 appears to be available for download, but only to European users that are capable of using Sony's Connect service, whatever that is. If I do not have the access (nor I intend to get one), will Sonic Stage not install, crash, bug me with error messages, anything else? TIA;)
