(sorry about the previous blank reply...hit the "add reply" button by mistake) Well, I did a complete uninstall of Sonicstage (as described by member kurisu), and then re-installed it (in case I accidentally deleted the driver for my unit), but still no luck. When I look under Tools, Options, Transfer Mode, there are no options available to me and no "Device/Media" show up. In terms of contacting Sony, they're useless. I tried about 6 months ago to get an upgrade of Sonicstage 2.0 (what shipped with my unit) to 2.3, so I could use the WAV Converter software, and all I got was form replies from both their phone and e-mail contacts. Nobody seemed willing (or able) to ship me a new CD upgrade, even though I was willing to pay! I've got a call in to a local Sony parts source for the latest CD, but haven't heard back from them yet. Thanks for your help, though!
