CrystalReportViewer showing blank report

[cdck]

I'm using Visual Studio 2008. I have a form which has a DataRepeater and a ReportViewer displaying a report which uses the same table in the local DataSet that the DataRepeater uses. When I load the form, I fill this table. The DatarRepeater displays the data correctly, but the ReportViewer shows a blank report - and I even have it refresh the report after the table fills.

Here's the load code:

    Private Sub SNoutput_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim MachineName As String
        MachineName = System.Environment.MachineName()
        Dim constr As String
        constr = My.Settings.M2MAydinOther

        Dim SQLstring As String
        SQLstring = "SELECT SN, PartRev, Contract, MfrDate, Model, Description, MadeIn, WhichLabel, '*' + SN + '*' AS SNbarcode FROM SerialSNsOut WHERE MachineName = '" & MachineName & "';"

        Dim con As System.Data.SqlClient.SqlConnection
        con = New System.Data.SqlClient.SqlConnection(constr)

        Dim da As System.Data.SqlClient.SqlDataAdapter
        da = New System.Data.SqlClient.SqlDataAdapter(SQLstring, con)
        da.Fill(LocalInfoTables.SNsOut)

        Me.cvLabels.RefreshReport()


    End Sub
