TH2 Sonar is now TH2 Producer-64

I started using TH2 in X2, and the pluging was referred to as "TH2 Sonar".
 
NOW, in X3 it's being referred to as "TH2 Producer-64" (Fresh install on a new computer), and my projects aren't recognizing it. It's saying the plugins are MISSING.
 
Is there a way to restore TH2 to these projects, with the settings retained? And WHY would the names be different?
 
Thanks,
 
Gavin

Ok I see what's happening.
 
I loaded the X3 demo, and IT'S using TH2 Sonar. I have Producer, as I've always used - and my personal projects are ok. It's just the X3 demo that isn't.
 
Duh :-)
