Import my preferences from C5?

Is there a way I can get all my preferences from C5 to import into C6?
I’m trying to chase the cause of an issue with East West Quantum Leap VSTi I posted about here :

and wonder if it’s some sort of change in preferences, because the problem doesn’t exist if I open a C6 file in C5 and resave it as a C5 file, then reopen it in C6.
