Reply to Single blue light of death?

Or am I just being an idiot?

Plugged in my MF Classic today and all I get is single blue left on the button in the top left hand corner. I have tried the four corners, I have tried getting it into boot mode using two pins in the red holes on the bottom - nothing.

It does not register on my system (no ding dong sound like other usb devices when they attach). I see nothing in device manager anywhere. The midifighter utility loads up, looks for an update and then just disappears.

Any ideas??
