MySQL [Warning] error

I would like to know, how can I fix this error?
Found in mySql error log [EasyPHP 1.8], appears all the time server is starting:

081105 8:04:49 InnoDB: Started; log sequence number 0 43634
081105 8:04:49 [Warning] mysql.user table is not updated to new password format; Disabling new password usage until mysql_fix_privilege_tables is run
081105 8:04:49 [Warning] Can't open and lock time zone table: Table 'mysql.time_zone_leap_second' doesn't exist trying to live without them
C:\PROGRA~1\EASYPH~1\MySql\bin\mysqld.exe: ready for connections.
Version: '4.1.9-max' socket: '' port: 3306 Source distribution

Try to remove application and run setup again and before changing default config try to look in forums how to change password or privileges.
