Installed a new version of CMSMS, installed CGExtensions, CGSimpleSmarty, 
FrontEndUsers, and Self Registration. I set up user properties and a group in
FrontEndUsers, then added the SelfRegistration tag to one of the pages. When I
navigate to that page, I get this error.
Fatal error: Uncaught Error: Class 'RRUtils' not found in
C:\wamp64\www\cmsms\modules\SelfRegistration\action.signup.php on line 89

I have searched through the code and cannot find a class with that name. I also
downloaded the tar files for CGSimpleSmarty versions 2.2 and 2.2.1 but the lib
folder is missing in both. Is that where 'RRUtils' was stored?

The site is on my local WAMP server.
