Reply to Midifighter not going into bootloader mode

Hi guys,

I got a serious problem: I was DJing with my two midifighters yesterday. One day later (earlier today) I set up in a club and one of the MFs is not being picked up. I try again unplugging etc a few times, then they are both being recognized in Traktor.

However only one of them is working. The other one is not responsive, however when i do the eco freeze effect or press sync on Traktor's deck it the LED of the MF is lighting up. But I can press any buttons and it doesn't react at all. The other MF is working properly.

After the set I tried to reboot the MF. First tried MF Update program (Im using MAC btw), then i tried the two manual ways with the buttons on the bottom side of MF.

Nothing is working!
Damn guys, got any idea?
I got a wild weekend of gigs ahead of which the next one is in less than 24 hours...

Would appreciate help highly!!!!!
