I had the same thing too. SX 3, Cubase 5 and 6.5 all under one license. Working well until I updated the eLicense software. poof… gone. All it shows is Cubase 7.5 and Halion Symphonic Orchestra 16 bit version and Halion Player. I still have Cubase 5 on my Mac and it is running fine. Cubase 6 is no where to be found on the machine…
