Hi Sturge This is the questions they asked me To enable us to investigate the problem you are experiencing with your NW-E405 and the supplied Sonic Stage software we need some more information. Therefore please can you do the following and advise accordingly; * Connect the NW-E405 to your computer. * Please can you let us know what is displayed on the NW-E405's LCD screen. * Click on the [start] button and select [My Computer]. * Please can you let us know which drives (including drive letters) are shown in this window. If the removable disk associated with the NW-E405 is displayed please can you double click on it and let us know what is shown in the window that opens. Then close this window. * Right click on [My Computer] * Click on [Properties] * Click on the [Device Manager] button * Go to the heading [Disk Drives] and click on the [+].

Please can you let us know which options are shown in the list that drops down. I replied with the correct answers and they came back a few days later with the below but by then I'd sent the MP3 player back and made a few comments about there device / software! I can only advise that you firstly try the NW-E405 in another port preferably on the back of your machine and then re-try. If you still receive the same Device Manager information as before then please follow the below and advise accordingly: * Connect the NW-E405 * Go into [Device Manager]. * Go to the heading [Other/Other Devices] and click on the [+]. * Double click on [Network Walkman]. Click on the [uninstall] button. Click [Ok] to confirm device removal. * Re-Start your computer with the NW-E405 connected and turned ON * Windows should detect new hardware and automatically install the correct drivers for the NW-E405 * Re-try the Walkman and advise accordingly? I must say the advice you gave me was a lot more helpful than Sony, many thanks fo your help
