okay, try plugging it in. Go to Startmenu, right click 'My computer', and select properties. Go to the 'Hardware' tab, then Device manager. Down at the bottom, you should see a section of the tree that can be expanded, entitled 'Universal Serial Bus Controllers' Find the Unknown device part. Select that, then go to 'Action','Uninstall'. After un-installation, the computer might restart. Unplug your walkman. When windows is back up, plug it in, and see if that works. if not, I have an alternative solution

Hi...I just found help on the sony support page www.sony.com. You can delete songs by going to MY COMPUTER and clicking on the walkman as a storage device and delete files right from there under the music folder. Your MP3 will update when you unplug it from the computer.

Hi,Convert the video to MP4, plug in the Walkman to your pc/laptop and drag & drop the video into the video folder.
I use WMconverter.
