[Solved] V-Vocal crashes both X2 and X3 now!

I had both Sonar X1 Producer 32 and 64-bit on my rig, then I purchased X2 Producer 64-bit and installed it on my computer, and they both ran well and co-existed for years.  When I purchased Producer X3, I thought, well, maybe I should uninstall both X1 versions to make room for X3 64-bit (leaving 64-bit X2 in place).  Everything seemed to go OK.  I installed X3 and it went well and seems to run well, except that now, V-Vocal will not run.  It crashes both X2 and X3.  Now, I'm wondering what went wrong...Any ideas?  Melodyne Editor v2.0 seems to work well, but I still have some projects that I need to finish up with V-Vocal.  Also, I had become quite proficient with V-Vocal and I sort of miss that tool.  Upon crashing, I sent the dmp files to Cakewalk, but no answers or solutions have been heard from them (yet).  

Thanks, Noel.  I was hoping that there might be some kind of solution to the problem.  You've given me hope.  I will post back after trying your suggestion.
 
Thanks.

I do not have X3 installed. You could validate V-Vocal function in X2.

Oh, by the way, it does work correctly in X2 now.  That's why I'm questioning if it is broken in X3...
 

OK, everybody.  I think I finally figured it out.  Earlier, I had broken up the vocal track into sections by splitting them in order to be able to work on short segments.  I then highlighted the short clip and opened up V-Vocal under Region FX.  Like I said, it did call it up, but with no pitch correction.  Then, I thought, maybe I should just drag the cursor across a section of the audio as if it were an unbroken, unsegmented track.  Voila!  It works.  So, it looks as if all I have to do is merely highlight the section with the mouse, choose Region FX and invoke V-Vocal and it WORKS!  Thanks to those who assisted me with this problem!

Let it go

And use Melodyne!
