Hi, Thanks a lot, but I finally found mine!.. it was in hard disk that I was using for storage in my old desktop PC. Then some time ago the motherboard had a serious problem, the PC stopped working and I decided to dismantle it completely. It had 3 hard disks inside, and I mixed them up and lost track of what was in which one. Only after mounting one by one in succession in an external eSATA box connected to my laptop was I able to see what was stored in each disk, and in one of them I finally found all my cubase 10 and all the updates from 10.0.20 to 10.0.50. All this just about 1 hour ago, just before I saw your answer here. Now it’s almost 04:00 am here, so I’ll try to install 10.0.30 tomorrow. But Thanks anyway.
