[Plugin: Paid Memberships Pro and Theme my Login] & Disabling WP Registration

I am using Paid Memberships Pro on my site. I use “Theme my Login” at the front-end for my clients to gain access to the paid content on the site. If a non-logged in user (aka potential client) tries to access the Membership-Only pages they get a message that tells them they need to log-in to view the pages. The webpage then gives them an option to “Log In” or “Register.” The problem is, the “Register” option takes them to the WP registration page. I have disallowed user registration which took care of the problem of the register button showing up on the actual Log In page, but the fact that it is appearing and redirecting my users on the Membership Only pages is a pain. Is there a fix for this? I would either like to disable the the “register” button or redirect users to another page on the site. Hope someone can help!
