Merge replication problem

Hi,

I created a merge publication on 2005 SQL server,

I deleted this publication and tried to recreated it and got following error.

An Exception occurred while executing a T-SQL statement or batch

(Microsoft.SqlServer.ConnectionInfo)

Invalid object name 'dbo.sysmergepublications'.

I tried this with a different publication name, it still did not work.

Please help.

Pingx
