computer not detecting my miniplayer [Solved]

i just got the miniplayer yesterday... and i was told to use up all the battery 1st before charging it

so i decide to put a few songs into the player (1st time i plugged it in to my pc) and it detected fine and worked properly

but now that i have depleted the battery
my cpu doesnt recognize it anymore (when i put the usb in
a bubble pops up..... it says usb device not recognize
and says that it is malfunctioning)
it charges fine but i cant get it to detect it .........
my player is on
any help ? thank you

hmmmm maybe the player was too low on battery or something... ? i finally got it to work
