Cannot Create Database Mail Account

Hello all,



I get a strange error message when I try to create a Database Mail account. I know the script is OK because it works fine on another SQL 2005 Server. This script is as follows:



exec msdb.dbo.sysmail_add_account_sp

@account_name = 'SMTPAccount01' ,

@email_address = 'someone@somecompany.com' ,

@display_name = 'Sales System - Company Name' ,

@replyto_address = ''someone@somecompany.com' ,

@description = 'SMTPAccount01' ,

@mailserver_name = 'somecompany.com' ,

@port = 25 ,

@username = 'someone+somecompany.com' ,

@password = '1234'



The error message I get is:



Msg 15466, Level 16, State 2, Line 1

An error occurred during decryption.



I tried installing SP2 and that didn't help.



Someone help please!



Thanks in advance.
