DB Master Key - Sql Server

[TimHop12]

This is not working with me on SQL Server 2005:

use XDataBase
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'password'
go

However it was given on MS site:

Please advice. Thanks.

actually the password must be > 8 chars and contain upper/lower case and numeric/ Non-alphanumeric characters.

Password = 'password' is used having exactly 8 chars,
i think this may causing the problem
