Hi fatharock-
Are you on Windows or OSX? If you are on OSX, Reaper should be able to locate the plug-in folder already, on Windows, you'll need to add the following custom location to Reaper's list of VST folders:
C:Program FilesCommon FilesSteinbergVST2Eventide (for 64-bit)
C:Program Files (x86)Common FilesSteinbergVST2Eventide (for 32-bit)
Instructions on how to use the plugin can be found in the manual, at ~/Documents/Eventide/<Plugin Name>/<Plugin Name> User Guide.pdf
Best,
Tom
