I just purchased the upgrade to Melodyne. However, after installation and when I try to open a new instance of the Region FX, I see the Melodyne field appear on the bottom of the screen for 1 second===and then it disappears. I have tried to scroll up and down, but can't seem to  find where it's hiding. At least I hope it's hiding; perhaps I installed something incorrectly. Does anyone know how to find Melodyne AFTER I've opened a Region FX on a song.

...Melodyne is light years ahead of V Vocal...

 
Maybe you are using an edition of Melodyne that you purchased separately rather than the one one bundled with Sonar. It can't do some of the things that V-Vocal does, e.g. curve drawing or formant control.

No, I don't think so, I purchased it as an add on to Melodyne essential, and it was called Melodyne Assistant. I was able to see it in the same pull down menu that I usually use. In fact, when Sonar first came on after installing the program, the  plug in detector said that it had detected one new plug in. I just have a feeling that there is a button or icon somewhere which should place the Melodyne view on the bottom of the screen--as opposed to its being hidden now. Of course, that's just a feeling, and I have no idea why I can't find it.

...Do I need to install all of Sonar 8.5 (my earlier version) in order to get V Vocal, or can I just install the V Vocal program found somewhere in the 8.5 discs?...I assume I can have both 8.5 and X3 (which I now use) installed on the same computer, and that installing 8.5 won't get rid of the X3 version. Is that true?

 
Install Sonar 8.5 itself but untick all the options for plugins and extras. It will install as a separate program without overwriting X3. However it may possibly overwrite a couple of existing registry entries, so to be safe it is advisable to reinstall X3 afterwards.

You might have to uninstall Melodyne essentials and reinstall Melodyne upgrade.
Region FX always open in the Multidock. It may be necessary to show the dock to see the Region FX.
If you can see the Multidock, Double click on the Region FX clip. This will open the ARA selection in the Multidock.

I did find the Multidock narrow strip at the bottom of my screen. I did double click on that, and a similar looking set of waveforms appeared on the bottom of my screen. HOwever, it doesn't look like Melodyne. At the very bottom, there is a small rectangular box which says, "loop contsruction," as opposed to Melodyne.
I did get another link to the new Melodyne in my Email, so I will try that now. ANd yes, I realize I might have to uninstall Melodyne Essentials. I must say I'm already getting a bit pissed that everything has to be so difficult.

I did contact the Melodyne support Email. Hopefully, in time, they will be able to help me.

If you are just looking for quick and easy pitch correction on any voice or instrument you could always export your audio and import it into the Reaper Daw and use it's REATUNE plugin "Which you can use for free for 60 days Free" although it still works with nothing changed after 60 days so I am told. 
 
Here's a video of REATUNE being used. https://www.youtube.com/watch?v=AVd8xpZ6rNU
 
Here's another one.

It wont let you draw pitch lines, but I get the impression that it is a little bit more harsh when it comes to pitch drift. You could always REWIRE and put the vocal track in REAPER and use REATUNE that way, or import the vocal track to REAPER and use REATUNE and export it back to however you wanted to use it. 
 
Interesting enough, Melodyne Essentials does work with AUDIO whether it's vocals or bass or whatever, but ONLY MONO.  Same with REATUNE by REAPER. 
 
Either way, I have no idea if this is relevant to what you are trying to do, but I thought I would mention this in case it might help you or anyone else interested in this subject. 
 
I am no expert, NOT AT ALL! But much like you I am learning myself. 
 
Good Luck!
