It did try it with a newly formatted device. Winamp won't even start with the 1.0.4, neither in Vista and XP With the winamp 5.33 and the old plugin it works fine in XP but not in Vista. In XP, winamp 5.33 and 1.0.4: - winamp do startup, but it won't find the plugin. When I go to the option menu/plugin, than it won't find ml_sony. I hope this information is useful. Do you know if there are s70x users who get the new plugin working? Do you know if there are Vista users who get the plugin working?
