Media not ejected propely during show

Last night during a show, I received this message 3 times… everything stopped… What can I do? Both built-in SSD and with a separate SSD

A little information wouldn’t go amiss. What Prime equipment were you using? What firmware was it running? What file type was being played? Presumbly you’re playing your own files, not streaming.

Oh yes of course, sorry… Prime 4, 260 gb SSD (4 years old) with the software version 3 3.0 and the latest… Even if I don’t choose a source, I get the same message. Own songs, no streaming

Is there anybody who can help me?
