OK Problem Solved
The clue is in the error message
\\.\pipe\com_paceap_eden.licensed_authorisation
Pipe is a software protection programme designed to stop illegal copying of software.
In my case the software was not up to date so I simply ran the iLok Licence Installer programme
and it updated the Pace software.
Now when I run Sonar Platinum my Softube plugins work.
However they still do not work in Sonar X2 Producer so I have deleted it.
The plugins still don't work in other DAW's I have on my system so I am not saying
the problem is fixed for anything other than Sonar Platinum.
