    Can you try setting the output parameter values to null and try again? You can check the VB code from : http://msdn.microsoft.com/en-us/library/ms252210(VS.80).aspx

    This has:

    Imports Microsoft.Reporting.WinForms
Imports System.IO

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ReportViewer1.ProcessingMode = ProcessingMode.Remote
        ReportViewer1.ServerReport.ReportServerUrl = New Uri("http://SSRSServer/reportserver")
        ReportViewer1.ServerReport.ReportPath = "/AdventureWorks Sample Reports/Company Sales"
        Me.ReportViewer1.RefreshReport()
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim warnings As Warning() = Nothing
        Dim streamids As String() = Nothing
        Dim mimeType As String = Nothing
        Dim encoding As String = Nothing
        Dim extension As String = Nothing
        Dim bytes As Byte()

        bytes = ReportViewer1.ServerReport.Render("PDF", Nothing, mimeType, _
            encoding, extension, streamids, warnings)

        Dim fs As New FileStream("c:\output.PDF", FileMode.Create)
        fs.Write(bytes, 0, bytes.Length)
        fs.Close()
   End Sub
End Class

    Please let me know if this doesn't work.

    Thanks
