CANCEL - I got a new password again, and now everything seems to be working fine!

I was in my Hostgator File Manager for one of my WP sites.

I double-clicked on the wp-admin folder.

Then I (accidentally) double-clicked on the admin-header.php

Now I can't log in with my normal password.

(I got a new password assigned, logged in OK, changed to my previous password, and was OK. But after logging out, it again won't log in.)

Any help?
