[Plugin: Better WP Security] can't access login page

Hey, I installed BWPS to thwart a hacker that continually strips my files & installs phishing scripts even after I change my login pass so naturally I did all the fixes within BWPS that I could including changing my wp- …extension? now I cant access the login page. I saved the extension that was generated but it doesn’t work & I don’t even know if I’m putting it in the URL properly or if I’m missing something. I don’t understand anything about getting into the database or accessing the .htaccess file, I don’t know if Mr. Hacker has expended my access chances that wre set to 10 or what error i would see if he had. I’m just getting ‘not Found’ in place of the extension
The bottom line is; I’m a non-techincal noob & I don’t have a clue where to EVEN start PLEASE HELP
Thank you
