Thanks again for the responses.
Like I stated originally, I've been using Cakewalk products since the first version of Cakewalk. With that said, I've been using McAfee as long as well. I've never experienced any issues related back to my anti-virus software.
At this time, I still have Sonar X2 Producer, Sonar X3 Producer and now Sonar Platinum all installed on this machine. 
X2 and X3 do not exhibit the issue, only Sonar Platinum???????????

I had lots of issues when I was using Macafee.. Since I changed to MS Essentials all's been good.

Sometimes I think McAfee is like a virus that you install willfully.

Yeah.

I wanted to thank Scook for the answer, which was very helpful.  I'm all set.
 
I had forgotten which thread this post was in, and couldn't find it by the title...

I also wonder if the project that causes Sonar to not be able to get restarted might have some 32-bit plugins in it, as sometime BitBridge seems to have trouble freeing up resources after Sonar ends, particularly with the audio interface, for some reason.
 
32-bit plugins in a 64-bit Sonar can be quite unstable, and lots of folks have made deliberate choices to move to either completely 64-bit plugins, or as close to that as they can get, and testing the remaining 32-bit plugins to make sure if they ARE still used that they seem to work.  
 
A lot of the companies that made 32-bit plugins have created 64-bit versions you can download as a free update, you just have to go look to see if they have done that.

Oh, yes, thanks.  My comment was an apparently too subtle attempt to encourage more descriptive post titles.
