GP...you have to be careful when installing some of these...
They will, by default create a "C:\program files\Steinberg\vstplugins" directory if you didn't specify during the install
where you wanted it to go.
I make sure I use C:\Program Files\Cakewalk\VSTPlugins as my directory of choice...
Just check to see where it installed and add that path to your Plugin Manager scan directories...
Hope that helps..
