It’s been 6 days and counting since I first contacted support about this, so I figured I’d try here. Since upgrading Cubase 4 to 6 on one of our studio computers (the only one running 10.6) I am no longer able to use Cubase 4 on any of our other systems which are running on 10.4. The issue as best I can tell, is that the highest version license software for 10.4 (5.4.20.01010) does not recognize the license database and the new Cubase 6 license just shows up as unknown. I really need a solution to this issue quickly as I am losing days of work. Has anyone managed to get the newer e-license software (6.1.4.1050) to run in 10.4? Any other suggestions? Thanks! ---
