I have an 8gig clip. SUddenly stopped playing in mid song. It had a full charge, but no music and wouldn’t respond to my button pushing. Finally managed to turn it off. It went through a slow motion “Good Bye” and ultimately went blank. Later I tried powering it up connected to the PC and not. Nothing. I finally managed to reformat it and it came to life but the text is scrambled and unreadable. It will play music, but it is pretty tough to navigate blind. Suggestions?
