No longer working with WordPress 4.2.1?

Hello-

I have a client site that is re-launching soon and gets a lot of free user signups (for viewing additional content) but the site Admin does not wish to receive an email notification for every user that signs up so this plugin seems perfect. I believe it was working initially when we first started working on the site but I have heard from him that he is still getting email notifications for each user. We are on WordPress 4.2.1 and was wondering if maybe this may have stopped working with the latest release of WordPress. Thanks in advance.
