Are you guys still talking about the freakin’ mixer?! (kidding) 
I’m finally back up, on 7.5.20 with my new DAW build.
I had to do a from-scratch install of everything (you know how long that can take) in Windows 8.1, only to find 8.1, several plugins and Cubase wouldn’t play nice.
So, I had to start all over from scratch with Windows 7.
Painstaking.
But, it solved most of the 3rd party plugin problems.
Since Microsoft doesn’t sell Windows 7 anymore (except in some “replacement parts” department) it’s nearly impossible to find a non OEM version of Windows 7 in the wild. So, I had to use the license from one of my other computers (that would be fine with my Windows 8.1 license). So, I had to setup another computer, too.
At some point there’s gonna be some music making here, I think.
