Reply to Midifighter Crash?

My midi fighter has stopped working!
Has my S4 and F1 and my MFC.
But then yesterday out of nowhere it stopped working!
Have not done anything special.
My MFC sends signals to tractor but nothing happens when i press a button besides the "Ctrl" button flashes.
Run with MF_InstantGrat_1_0_3.
Tried to import the tsi file as usual without much success.
Very strange that it just stops working!
What do you believe I should try?

Must fix it. I'll play at a wedding in a week!!
