Thank you for your response. No, I did not try that for the reason I was too scared. I also wrote to MOTU support, opened ticket but that was useless, they never responded. But I have a new development a member recommended me to go to logic pro x preferences and disabled control surfaces. I did that and after that my projects are working fine. I will keep on aggressively using my DAW, and as soon as I feel sure & comfortable about the reliability, I will take the next step. As I eventually I do need to use my magic control surface
