WITH (Common table expressions) only works in SQL Server 2005 or above.

Even at compatibility level 80, WITH statements work in SQL Server 2005.

• Check that you are not running SSMS 2005 against a SQL Server 2000 instance.
• Check that your server has only one instance of SQL Server, and it is the 2005 instance.
• run this to check

select @@version
