OOoops!! Ok Login to your Cpanel, click on phpmyadmin, select the joomla installation database, find and open the users table, open the admin user configurations, check on the password and you will find a strange combination of letters and numbers this is because you cannot get your password back but here is how you will manipulate it. change it to '21232f297a57a5a743894a0e4a801fc3' without the quotes and click run.
Now go to your whatever site dot something slash administrator and use the password 'admin' without the quotes. Wow! you can login again. Change the password immediately. Good luck!
