Well...I can't speak for the OP...but I've found
my problem.
It appears that the "front door" for Style Dial FX (on my system) is in...
C:\Music\Applications\Cakewalk\SonarData\
SONAR Platinum\Style Dial FX
...it
was in...
C:\Music\Applications\Cakewalk\SonarData\Style Dial FX
...but it couldn't be found there.
Most everything else in this directory pile is located via registry entries (see Preferences/File/Folder Locations). This one is apparently hard coded (as I rather expect new ones going forward will be).
