Problemas con MySQL 4.1+ using the old insecure authentication

[Murallitz]

Buenas tardes, hice un upgrade del EASYPHP y ahora al ejecutar mis paginas sale este error. Estuve viendo en internet y varios dicen que debo cambiar el my.cnf y poner el old-password a 0.
Pero no encuentro ese archivo solo encuentro el my.ini y ese notiene esa parametro.

Adjunto el error espero me puedan ayudar.
GRACIAS!!!

Warning: mysql_connect() [function.mysql-connect]: mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool to reset your password with the command SET PASSWORD = PASSWORD('your_existing_password'). This will store a new, and more secure, hash value in mysql.user. If this user is used in other scripts executed by PHP 5.2 or earlier you might need to remove the old-passwords flag from your my.cnf file in C:\Program Files\EasyPHP-5.3.3.1\www\ScoreboardWeb\Connections\rsSB.php on line 14
