I inserted the LP MB and pinned the plugin. I then inserted the LP EQ and Sonar froze. I had to kill the program using Task Manager. I also had to log off and back on to completely kill the SONARPLT.exe process. It appears you can only have one of the plugins visible at a time. I was able to duplicate the bug.

What else is going on in your project? I did what I think was exactly the same procedure (insert MB, pin, insert EQ in same track) and it worked as expected, with both plug-ins visible.

It has several plugins in the project. I will try it with a very simple project.

I just tried it using the normal template which has no plugins and the same thing occurred. 
 

I forgot to mention that this was performed on a bus, not a track.
 

I just tried it on a track and the same error occurred, frozen program. This system is only used for recording and video editing. 
 

You're not the only one experiencing problems. Seems these plugins use a different protocol, I don't know why, but it was reported in another tread some strange happenings. I can't get either to show up, just a blank box where the LP should be and it's nothing I can do about it outside of buying a new computer because it's a graphics issue. Not too pleased about that at all. But life goes on...sadly :(

Thanks Jeff, this is why and trying to do my part to help the bakers improve my favorite DAW.  

What happens if you try inserting the two plug-ins in an existing project, not one from a template?

I tried it with an exiting project first in order to run some test. I then tried it using a basic template after reading that you did not have a problem.
