"VPA plugin rejected...." SampleTank 3 issue

When Sonar starts and goes through all the plugins I get a dialog box that says "VPA Plugin rejected VPA Host."  When I click OK I get a much larger box with a lot of information, including "controller > initialize" and two choices:  Ignore (or delete the plugin, I think) or something like OK (I'm at a different computer now) and the phrase "risky".  It's for SampleTank 3, and I decided to click "risky", and there was no bad effect on ST3.  I still get the messages.
 
Any idea on how to stop this from happening?
 
Thanks,
 
Steve

I use ST3, and stevec is correct, the VST2 version seems to be more stable and usable.  My issue with the VST3 version is that only outputs 1-16 sent out audio.  Any sounds routed out of 15-32 didn't make it to the instrument track.  I don't have this problem with the VST2 version.  You might try loading the VST2 version and see if that helps.
