Sorry for before... I don't really know what you mean by operating system so I write this: Well I have windows XP. Intel Pentium, 4-Processor 540, 1 GB DDR, 250 GB, ATI RADEON X600 PRO and USB 2.0. Programm I am trying to use: SonicStage 3.4 I have a NW-HD1 (MP3-player)... 10 MBIT, I use AVG antivirusprog., (((If needed to know))) Don't know what more to tell you guys, only that the SonicStage ain't working... Is I have told you before, when I try to start up the programm it only says: "Updating SonicStage database SonicStage will be restarted after the updating has completed". And the sh*t won't work. Tell me if you need any more fact.
