Whenever I attempt to drag and drop several songs into WMP and click the sync button it says it has put just one song on the device and for the rest of the songs it shows me a error. However, when I disconnect the device and look in my music, there is no music on it. Before I did this I did format it, could this be the problem? Also, I checked to see if I needed new drivers and it said I didnt. Ive never had any problems with my mp3 player until now.
