XTouch Scribble scrip not displaying

New

Hi guys, I worked on my XTouch with Daw (Magic Samplitude) some weeks ago, everything was fine. But I wanted to start a mix now and discovered that the scribble scrip, channel meter, timer (SMPTE) screen not working. Faders and other buttons worked.... every means of getting it working failed. What could have been the problem and likely solution pls?
