I’ve used cubasis since it first started, I hate all the constant upgrades. It’s like re-learning things every time, which is why I hope you can help me please. I have cubasis VST 5, the software the dongle, the lot, I’ve used it for years, but have recently upgraded to a new computer and NO ONE and I mean no one can help me get this software to work because I have lost the serial number, even the original provider cant help me. Does anyone here have any advice other than “Tough luck! Buy a new one”?
