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.

I do not work here, but the benefits are still awesome
