So, I've been using the various versions of SS with my MZ-NH900 for a few years now. Recently, on a computer (850MHZ P3, 768M ram) that I've just reinstalled W2k (SP4) on; SS 4.x doesn't work. I've tried uninstalling 4.x, and reverting to 3.4, but both versions of SS give me the exact same error: While transferring .mp3 files that are saved on my HDD, SS closes. Transfer begins, file conversion starts, but SS closes before the transfer completes. Tried different MDs, tried formatting the MD, both thru Windows and SS, tried different USB port... 3.4 throws the omg error, then closes, 4.x just closes without any errors. Anybody have a similar problem? Thanks, BSW
