Big Midifighter problem

Hello,

I've got a big midifighter problem.

Since I've used the new mapping, which by the way is awesome,
my midifighter doesn't work anymore.

I have updated my midifighter manualy, because the automatic
update didn't work. So I downloaded the .hex file and updated
the midifighter so I could use the internal midi mode ( the 2 lights
on right side of the second row ).

The problem is that is started up my laptop today, attached the midifighter and the only thing that happens is that the led in the top left corner is on.
I cannot switch it to another button. It look like it's stuck. I can't get into
menu- or bootloader mode anymore. It looks like my laptop doesn't recognize the midifighter anymore.

Can anybody help me? Is there some sort of reset button I can push?
