FWIW, I don't have a C:\Jbridge folder
First thing I'd want is to know is whether JBridge works, then (if it does)

On my system the Red plugins seemed to have installed to
C:\Program Files\Steinberg\VSTPlugins
This is a common location for VST installers

You may want to try adding the Red VSTs from that folder, if it exists and is different than your original 'Add VST' folder.

Make your sound your own!
