Elektron Musical Instruments

My MD is only 20 hours old. I was playing a pattern 
when ..................... 4 tracks just go silent all by themselves.
Tracks/buttons 13-16 all went silent during playback. I look at the 
buttons and the LED's are still blinking along with the sequences 
that WERE there. HERE IS THE SCARY PART... I go to edit track 13 and 
there are no parameters anymore just 8 blank boxes . All the parm 
icons are gone , the only graphic left is the volume meter. Same 
thing for 14-16 all blanks.
DID THIS HAPPEN TO ANYONE ELSE?
ANY suggetions anyone??
