If it says that, then the password isn't matching the encrypted password stored in the database.
So, that suggests that either your configure.php database settings are pointing to the wrong database and/or db-prefix,
or you've reset the password and aren't using the new one it generated for you.

You posted earlier that your DB_PREFIX is "zen_", so that means your admin is looking only at tables named "zen_xxxxxxxxxxxx". If that's not the right set of tables for your store, then it won't give you a valid match on passwords, or anything else.
