updated to Melodyne 4, and things not working as they should

Running X3 Studio, and I just updated to Melodyne 4  - I'm running the Assistant version, if that matters.  After starting up Sonar, I noticed that now the Region Effect option is ghosted out.  I can drag the Melodyne effect to a clip and transfer manually, the old-fashioned way. But then two other problems occur:
 
Used to be that double clicking in the Melodyne window started playback at the clicked location.  It doesn't do that anymore.  I have to click in the track window to start playback.
 
Second, it used to be that clicking and holding a note sounded it.  Doesn't do that anymore either.
 
I can't find anything in the options or buttons to turn these things on or off.  If memory serves, they were default functions in the old Melodyne.
 
Any updated to version 4 with similar problems?
 
Thanks guys

Thanks, scook.  I thought I was running X3e, but it was X3a.  So I ran the update to X3e, and still no ARA option for Melodyne.  So then I uninstalled and reinstalled Melodyne.  Still same problem.  Anything else I can check for?
 
Thanks

It shows up as VST3 in the plug-in browser, and that's the only version installed (64-bit, same as my OS and Sonar). Still no ARA access.
 
EDIT: update - I uninstalled Melodyne 4, and reinstalled Melodyne 2. Now it won't activate with my serial number. I've dispatched an email to Celemony.  ARGH!!
