As an ex Pirate I can tell you luck will only aid you in finding what actually exists. Cubase 9 would be the rarest of treasure, found by following the blankest of maps, read only by the dead, after canceling out the entire universe with a phase inverted copy of itself.
Cubase 5 was the last i heard off, but my sailing the seas for rare pearls ended quite some time ago!
Edit: actually I just looked on youtube and there seems to be quite some videos about it. But still… threatening to use pirated software as a response to a lack of response is no way to act. You go join the Pirates if that’s where you feel you belong.
