ASP.Net Error: System.Data.SqlClient.SqlException: Invalid object name tblRSS

I have uploaded a site with database on smarterasp.net Hosting and I have created RSS page for the site but when I try to access this page this error appears:

Invalid object name 'tblRSS'.

my code is :

Dim dt As DataTable = New DataTable()
    Dim conn As New SqlConnection("Data Source=SQL7002.site4now.net;Initial Catalog=DB_?????????;User Id=?????????_admin;Password=???????????;")

    Using (conn)
        Dim ad As SqlDataAdapter = New SqlDataAdapter("SELECT * from tblRSS", conn)
        ad.Fill(dt)
    End Using

I'm sure the tblRSS table exists, can you help me?
