I was trying to use Rapture Pro for the first time, but I kept getting drops outs. (Some notes played and some notes didn't.) All of the sudden I got a message to log in to the command center and activate Rapture Pro. It said it was currently running in demo mode and I would get some drop outs. I logged into the command center, but I don't see any way to activate it. There is a serial number. Do I need to enter that somewhere? It was installed from the command center and all my programs were green, so I have all the latest versions.
 
Or does just logging into the command center activate it?
 
Thanks.

It appears to be authorized now. All I did was open the Command Center and that must have fixed it. I can see my serial number on the about page and it plays all the notes now. Great sound on the keyboards anyway from what I've heard.
