today I switched on my keyboard and it freezes while loading the first block of instruments (pianos etc).
On the screen top, on the left side an orange bar appeared reading:
"" ARM CPU DATA ABORTED "".
A cold whack goes my spine down

I turned the mains off, and after a few seconds on again with the same result.
What happened? Saturday it worked perfect an normally.
Any ideas?
If this have a 'users solution' I appreciate a hint how to proceed.
Thanks!
