This is well over a year since the last post on the SAVR/Music Library topic, but I thought this might help out. I have just upgraded my controlling PC to an Intel I5 with 4Gb RAM and 64 bit Windows 10. The new PC, as did the old one, came with a serial port to control the SAVR box and the Sony CDP-CX455. I have found most USB-Serial converters to be somewhat flaky. It all works well, even with the latest 64 bit Java software.
