You have to put the player in MSC mode by going to Settings-->USB Modes. Then your computer will recognize it as a Removable drive in My computer. You can't see it in the Media Converter program.
A couple of other hard-learned lessons:
1- You can only use music on the removable drive. Pictures and video have to go through the converter first to be usable and can only be stored on the internal storage.
2- The microSDHC cards don't work. I tried a high capacity 4GB card and had to downgrade to a 2GB microSD before it would work. Works like magic now!
What you do is get a micro sd adapter and plug it in try that!
if theres a slot for an sd card on your computer you need a micro sd card adapter. if it doesnt have an sd card slot you need to buy a usb memory card reader (making sure it takes a micro sd card first)
both are widely available in supermarkets/electrical outlets or on ebay/amazon/play etc and are very inexpensive.
