Membership plugin has a redirect

I am trying to lock certain pages (paid content) in doing so, there is now a redirect I can not login to the WP admin panel. What can I do to reach the admin panel?

Link: http://absolfit.com/

<click> Login from the menu => Already registered? Click here to login.

You will see the URL has a redirect which comes right back to this page. I need to reach the WP admin panel.

I was trying to upgrade to Membership Pro when this happened.

The content that is to be locked is "Jump Start" and all sub-pages.

Please respond as soon as you can as my content is now open for free:disappointed:

Thank you in advance,
Barb
