[Plugin: Hide Login] Can Not Display Log In Page

I just activate this plug in and set it using default settings. After log out, i can not login to my wordpress admin with http://mysite.address/login Also I can not access http://mysite.address/admin. This plug in did not work.
Then i resolve this by reset my .httaccess, i can login with /wp-admin again. I try to setup my hide login plug in again. Nothing different with my first try.
