Force Email Login

Had to FTP and delete plugin to login again. Maybe if it was kept updated? I hate giving bad reviews to plugin makers, esp if they do it for free, but it failed identically on two WP sites, in same exact way. See screenshots of me trying to login with email AND username. With email http://tucsoncomputerdude.com/force-email-login-via-email.png With username http://tucsoncomputerdude.com/force-email-login-user.png By the way, I only have one user in this WP install. and am using Wordfence security.
