@AlexS , No, I can't say for sure. However, I bought my Expert Pro 220 CI in December 2018. From then until the update in mid-February this year, I experienced this error 6 times I think. After the update I have not experienced it for a single time so far, fortunately. And lately I have used the amplifier a lot. Hope it stays stable now. And... I also hope that I don`t jinx this now ;-)
