MP4 Player LGMP3 B803 act_v9-0.50
 

I have aB803 v9.0.50 player and when I try to access music I have downloaded I get a "Disk Empty"? The rest of categories seem fine. Can anyone shed any light as to this problem? I know that when I used Windows Media Player to shuffle music from my library to my player, I think I inadvertedly deleted the files under music....could that be the problem and if so, how do I get those files back.
