I can't find the other thread where Noel said to install with defaults - but I just looked through my registry and found all kinds of crap (especially in HKLM) that was pointing to various SONAR 8.5 and SONAR X1 folders!
 
(I was wondering why the content kept installing in a Platinum folder under my X3 content folder!)
 
Maybe it's not such a great idea to import old settings :-\

I never import settings, prefer to start again and do it manually. If anything it's an opportunity to review what you have, and removes any.possibility of the upgrade getting muddled
.

Well, it sounds like that's the way to go.
 
I just hate having to redo everything you're comfortable with (and have probably forgotten how to set up in the first place). Mind you - that's the good thing about SONAR staying on the same "version" now ;-)
