i had some issues from passing from 7.0.1 to 7.0.2.it drived me crazy all night,things like bad calour settings,no more knoobs in the mixer & some other issues.
So i went on the download center of steinberg ,and i downloaded the install core data for cubase 7.
i installed it on top of the cubase update 7.0.2.
And by magic,everything seems to be working perfectly.
i hope it helps some of you out there.
