Hello, I just recently replaced my computer and ran the SonicStage Backup tool to restore my library to the new computer. The restoration went without glitches. However I just discovered that a bunch of my tracks are gone. They are still visible in my library in SonicStage, but they can no longer be played or transferred to my Network Walkman (SonicStage reports that the files are missing). I can open up the storage directory in Windows, and indeed, the corresponding (physical) OMA-files are missing. All my albums have been ripped from my original CD's. I have never downloaded anything from Sonys Connect site, so none of the tracks are DRM'ed. The strange thing is that in some of my albums, a few of the tracks are still there, while the rest are gone. They were ripped from the CD at the same time, so I have no idea why some of them remain and some not. I completely removed the storage library and performed a new restoration, but the very same tracks ended up missing again. I suppose it was the backup operation that failed and left me with an incomplete backup. This definitely makes me worried about the reliability of the Backup Tool. Anybody ever encountered anything like this? (BTW I am using SonicStage 4.3 and Windows Vista 32-bit Ultimate Edition) Tom
