I have an unusual issue with a particular VSTi plugin.  I have had the issue with both X2 and with my very new X3 upgrade:
 
Last week, I got Sonivox Eighty-Eight 2.0  I installed it and activated it.

Since then, I have been unable to load the VSTi in Sonar.  (First with X2 and Now with X3).     I have it in a place where it is scanned by my plugin manager. 
 
When I go into a project and select Insert a soft synth, it is not listed.

The strange thing, however, when I go to Plugin Manager, and look at the master list of my VSTi Sytns, it is listed. 
 
A couple things - My initial scan of the Synth was done before it was activated. (I have scanned it since activation) I am not sure if this is an issue.

Second,  the Plugin Manager seems to take longer while it's scanning the particular dll file for this Instrument.

Any suggestions would be greatly appreciated. 

By the way, I am really enjoying X3.

When looking in the Plug-in Manager, is the "Show Excluded" option set? When performing the rescan, did you use the reset button in Preferences > File > VST Settings?

I should have mentioned in my original post - The plugin in question is not on my excluded list.
 
Thanks.

Are you using the "Default All Plug-ins" layout?

Yes, I am using the Default plug-in layout.   Should I not be?  

It just deepens the mystery. The plug-in is enabled in the Plug-in manager. You are using the default layout. The plug-ins were reset and rescanned.
 
Sounds like a call to support may be in order.

I doubt it would make a difference but if you are not running SONAR as administrator, you could try it.
 
edit: yea for some reason, I have supervisor on the brain fortunately someone is quite to correct me although I doubt it would matter either way

In the Plugin  Manager, you say it is in the master plug in list, but does it also show in the list to the right that displays the plugins in the default layout?

It does not show up on the right side - In both on the default list of VSTis or the custom list I made.
