Error en mysql

[yaviz]

Hola,hase unos dias tenia el problema de ke me daba este error:

Warning: mysql_connect(): Client does not support authentication protocol requested by server; consider upgrading MySQL client in c:\appserv\www\consulta.php on line 8
No pudo conectarse : Client does not support authentication protocol requested by server; consider upgrading MySQL client

me dieron la solucion ke era la siguiente:

mysql -u root-p

SET PASSWORD FOR basedato@localhost = OLD_PASSWORD('password');

de tal manera ke el my.ini me kedo asi-->



#This File was made using the WinMySQLAdmin 1.3 Tool

#Uncomment or Add only the keys that you know how works.

#Read the MySQL Manual for instructions


[mysqld]
default-character-set=latin1
basedir=C:\AppServ/mysql
#bind-address=
datadir=C:\AppServ/mysql/data
#language=C:/AppServ/mysql/share/your language directory
#slow query log#=
#tmpdir#=
#port=80
#set-variable=key_buffer=16M
[client]
default-character-set=latin1
[WinMySQLadmin]
user=basedato
password=contraseña
mysql -u root-p

SET PASSWORD FOR basedato@localhost = OLD_PASSWORD('password');

Server=C:/AppServ/mysql/bin/mysqld-nt.exe


Y al fin me funciono.
Pues hoy al volver a usarlo,no me funcionaba y me volvio a dar el mismo error,lo desinstale todo y lo volvi a instalar ,poniendo esas dos lineas en my.ini,,,pero nada ,,no me funciona.
ke puede ser?
