Did the update - complete and total waste of good time. My Rapture Pro still says it's registered in the Command Center, but I start it and it says I'm running a demo copy, making it unusable. I exchanged numerous emails with CW tech. support a while back to try to resolve this. At some point, they just stopped communicating - got tired of not being able to solve the problem, I guess, and decided I should just be stuck with a useless copy.
Fortunately on the fairly lengthy list of synths I have on my DAW, RP is *far* from the top in terms of my appreciation level.
