SOLVED - see next post.
 
I have Melodyne Editor version 1.0.8 from 2010.  It was not installed after I rebuilt my boot drive.  I do have SONAR X2 installed and am ready to install X3. 
 
Should I install Melodyne Editor first, get the update to version 2, and only after that install X3?
 
Or can I install X3 now (I'm anxious to try it out), and install then update Melodyne later with no difficulty?
 
Thank you.

This says I should update Melodyne for $49 first.
