Melodyne Essential stopped working for me? Cakewalk Help Please!!

A bunch of views here today.... nobody has any ideas what I should check?

I am adding melodyne to a vocal tracks fx bin, opening it, then you hit transfer, then play a segment of the song. Melodyne takes a second when you stop play to read the data and spread each blob out to the note it is closest to. Generally you can then move each blob around to tune them or do a group of them. Only I can't. That's the problem.

^^^^
This.   Just be sure you have the VST3 version of Melodyne installed.

Try what Sanderexpander said.

Azslow3 - Thanks!  Yeah I had it set to percussive somehow.   and thank you to everyone else as well,  ARA format is much easier!   Got it working like a champ.
   Here is the only other issue I run into and it is more due to my lack of traditional musical training...   Figuring out if the scale that melodyne has selected is the correct one?   I played some clarinet/sax as a child and don't remember much from that but otherwise I have never been classically trained on any of the instruments I play.  My father taught me the 1st few chords and how to tune a guitar, after that I quickly learned my favorite records by ear (thankfully I was gifted with a very good ear for that) and I would sit and make up riffs myself like most do.  I learned bass, drums, vocals, and some keys the same way.   I do know the notes and chords on the guitar though I have to stop and take a second to tell ya what chords are in a given song I am playing,  I also tune my guitar 1 full step down so I also have to transpose it in my head.  (a D chord on my guitar is technically playing a C, a G is really an F etc.)    Do I just figure out what the 1st note I sing is to determine the key of the scale?  (boy, this is the most Newbie sounding question I have asked on here in freaking years!)   
   All I know is, I was playing around with trying to use melodyne on a copy of a vocal track to generate a harmony to see how it worked, Not well, but I think it is because I have it on scale snap and it was the wrong scale.
