Reply to MF Stuck after 4 corner procedure

Hi Guys,

Unfortunately I ran into a problem with my beloved MF Classic.

During a gig, while I was playing, the MF start to respond strange, I mean that when pressed the shift+"RED BUTTON" (deckalized mapping) buttons for example, to engage the hot cue mode, the led does not lit up as they should to indicate the mode, the same for the slicer mode, even if the mapping works, I can actually juggling with the cues and use the slicer, and ALL the led lights up when pressed.

I tried to change mappings, reinstall Traktor 2, redownload mappings but nothing changed, so I tought to update the firmware. As first I tried with the old utility (MFUpdate), clicked on "Update Midifighter" and followed the 4corner buttons procedure but I received this message:

and now the MF is stuck with all the led light up except for the third of the third row.

How on heart could be? I tried to search in the thread already opened but I haven't found anything...

PS I tried also with the new config utility but the app says "No midifighter connected"

Please could you help me???
Thanks a lot guys!
