Melodyne Bounce to Clips wav disappears/Song won't render-SOLVED

Hey everyone.
It's been a while.
So, am coming to the end of a project and all has been well except this one song. It has intensive melodyne edits in the chorus because of multiple back up oohs and ahs with pitch correction and also lots of volume controllers because so many different types of parts. First thing suspect is that when you try to bounce the melodyne clips the wav form disappears (still the grey wav picture is there but not the wav form) and the sound also is not there. If i "unbounce" then sound and wav is there. So, gave up on that and left them as Melodyne clips. However, when trying to render even at audible bounce raising my latency from 128 to 1024 samples, when it comes to those chorus parts it starts stuttering and won't render. Ok, I have been doing this long enough to know that it might be a certain plug-in (I use anything from Waves to Omnisphere--in this project). I dumped the Omnisphere tracks because they can be problematic at times, but it is not the issue. The fact that the Melodyne won't bounce to clips is suspicious. So, of course, I can just take the region FX off, or even to go further, copy everything into another Sonar file, but wanted to check if anyone else has had this problem with Melodyne before I go to all the trouble of losing my mix parameters and have to start again.
 
Thank you
 
PS--May be I should add here I have purchased Sonar Platinum but waiting to install on new system. I am using Sonar X3 Producer latest version.

Nice to see you back - It's been a while since I was here much too.  Hope things are going good for you!
