Here is exactly what the VST Plug-In Error window says;
 
The following VST plug-in failed to load:c\program files\cakewalk\shared utilities\internal\PC2ALevelingAmplifier\
PC2ALevelingAmplifier_64.dll
 
I haven't got to go through much else to see what else is wrong or if it's consistently failing.
 
Can I just simply reinstall it?

Doubt it could hurt. Or install the CA2A, it is supposedly a drop-in replacement for the PC2A.

Thanks Steve. I think I have both, but can certainly download them, to try it again.
    I just noticed that the sections of the project that won't play vocal with Region FX open, will play the vocal track where I haven't converted to RegionFX yet. So, there must be some sort of ARA issue? I was tuning these two tracks of vocals and the clips that I haven't got to yet, play audio, but the clips that ones (verses) with Melodyne/RegionFX won't play audio.
 
As Beepster pointed out, I did save this project with Melodyne Editor open. I didn't think I had to "bounce (each clip) to track" till I wanted to, but I haven't noticed anyone else talking about it.
By the way though I have installed the Foxborough, this all started a couple weeks ago.

The CA2A was an update to the PC2A so you can't have them both on the same system. The installer of the CA2A gets rid of the PC2A.
Also the CA2A has a VST3 version as well as VST2.

Forgot to mention. The CA2A is generally considered as an excellent LA2A emulation, up there with the best, not quite so with the PC2A if that's any help to you.

You're right Mike. I updated it as soon as the CA2A came out, because I would love to have a real LA2!
I'm downloading it at the moment.
 
 

OK    I was way off base!   All my tracks have the CA2A, as I had upgraded it whenever it came out. So the notice that the PC2A failed to load is weird. They are old tracks/projects but all have the newer plug.
 
Now the problem is the CA2A are not there either, certain tracks have them greyed out and my mix is all off.

So, I've reinstalled CA2A and now that is working.
     I've discovered that if I bypass Melodyne then the clips (in question)do play.
So, .....reinstall Melodyne Editor2. whatever??? Too bad I have to do that from Melodyne Essential and then I wonder how to upgrade it? I bought X3PE with Editor as a CW deal. Hmmmmm
    I realize this should have been in the Problem Reporter section. OOOPS

No need to do various install of Melodyne. All version use the same installer. It's your serial number that determines the program features that get unlocked.

Fair dinkum?! Thanks Mike.
 That's a relief and I don't always think of that like T-Racks or PSP stuff, which is the same.
At least I feel like I'm tracking down the issue and figuring it out, sort of! LOL
