Reply to Problem with my Midi-fighter Classic

Hey guys I've been using my midi fighter for a good 3-4 months now but all of a sudden it has stopped working and right in the middle of use. Now, whenever I plug my USB into my computer, I receive the message, "USB Device Not Recognized, One of the USB devices attached to this computer has malfunctioned..."

Also I would like to note that the start up LED's are working fine but instead of staying lit up on my play/pause button, (the top right) it flashes between the two on the top left and then stays on the top left (my shift).

Any help is appreciated! Thanks!
