thank you so much, and incredibly generous with your time to respond so quickly
just thinking back this to this morning, when i plugged it into the computer, it didnt come up as it usually would, so i unplugged it and changed USB ports and the screen when glitchy, as in the usual screen went blurry so i did the usual reboot holding down both buttons and then this all happened......
so still just restart from scratch? its all backed up audio files anyway...... 99% sure
