Platinum Tutorial Content causing Sonar to crash.

I've been checking out the new content after installing the latest update and have encountered a funny one.
Using the browser to locate SONAR Platinum>Tutorial Projects>Instruments Platinum and loading it I can play the instruments for a few moments but then they will be silent as Sonar has stopped responding. I then Task Manager it closed, load Reason to get the sound engine going again (else Sonar sits in Task Manager doing nothing), close Reason and reboot Sonar.
It also can crash Sonar (a not responding message pops up) rather than just stopping.
 
If I then load the same kind of project (Instruments Producer) from the X3 Producer location it works perfectly fine.
Both projects have a warning that a multisample is missing from the "F" drive when it loads the project (not that I have a "F" drive) and they appear to be identical - so why is the Platinum one crashing?
 
Grum.
 
Edit:
 
My wife walked in as I just finished typing the above so I thought I'd show her it locking up and now I can't get it to stop working!!! It crashed 3 or 4 times on the trot and now it works fine. Freaky stuff indeed.
