Thank you for responding to my earlier questions.
 
It would seem something is not set up properly, but I do not know what that would be.
 
I am able to insert Pentagon and play it just fine.
 
Sorry - I have a couple more questions for you.
 
1.  When you installed Sonar, did you use the explicit Run As Administrator option, or did you just use a user account that had admin privileges?  (These are 2 different things)
 
2.  Did you have any antivirus software running when you installed Sonar?

Point 1 above by Bob is very important...

And you also need to make sure that you have set X3 to run with Admin
privileges...

Alex?

Generally, for pentagon to work, SONAR must be run as administrator.
WRT the other DXi plug-ins, if they work in a new project and fail in an existing project, that would point to a conflict with other plug-ins whatever they are or another plug-in requiring admin rights. Still don't know if this is a is 32bit or 64bit SONAR install, a transition from 32 to 64bit or anything about the platform.

Bapu - Alex has been through the wringer lately - let's give him the day off....  :)
 
I always run Sonar with Run As Administrator set, so maybe that is something different, as it does work just fine on my system.
 
And, some sort of conflict may well be in effect, as I understood the OP to have indicated that TTS-1 runs when in a project by itself, and that they fail when some set of plugins is also loaded into the project.

unhelpful and unfunny

Whoops,, erase wrong info. 

Post #3 suggests an RME interface although more detail about the hardware, OS and DAW software may be useful.
