Service Broker Not Working For Restored Databases (SQL 2000 Databases Restored On 2005)

I just restored my SQL server 2000 database on the SQL server 2005. after this i ran the Service broker sample ("Hello World") on this database by changing the AdventureWorks name to the new database name. The "setup.sql" runs fine. When i run the "SendMessage.sql" i was not getting any rows in the output (The message was not getting inserted into the queue). I checked the Service broker is enabled on this databased using the query "select is_broker_enabled from sys.databases where name = 'newdbname' " It was 1. I even tried the ALTER DATABASE SET ENABLE_BROKER. but it didnt work.

When i tried the sample on a newly created database it worked fine.

Is there any solution to make the restored database to work for service broker.

Thanks
