Reply to Midifighter Mk 1.3 works just few days

Hey Guys! First i have to say the Midi fighter is a really great and cool tool! I love him very much! The midi fighter arrived last week and works great! Today in the morning he worked! I wanted to use him in the evening, and ... he dident worked! I plug in the USB Cable and all lights are blue but the top-left-second is dark! i can push every button - nothing happens! I tried a reset with a peace of wire! i tried to go to the boot mode - didnt work, my pc didnt say "Hey u plugged in a Midi fighter" - i plug in the cable - lights on - nothing happens... :eek: :eek:
