Reply to Plug, yes. Play, not sure.

Hi dudes! I have some issues with my midi fighter.

I played for 3 months but yesterday it simply stopped working. When I plug it, the led routine happens but then, nothing. It don't even light up when I push the buttons.
I tried to plug it while holding the four corners buttons and using Midi Fighter Utility to update it but the checkered pattern simply doesn't appear.
I also tried to follow both of theses threads: http://www.djranking s.com/community /showthread.php?t=36611 and http://www.djranking s.com/community /showthread.php?t=13273,
but it didn't work.

I also tried to re-install windows. I believe windows assigns the midi fighter as a wrong device (like storage device or something) by installing a driver and it prevent the midi fighter from working as a audio usb thingy.

Have you got some idea? My Os is windows 7 Ultimate.

(sorry for my english, I try to do my best)
