Weird error. I must be missing something.

[MrCrispy]

ok, this is the code I'm using:

Sub page_load()
        Dim rptReport As Report = New Report(New PdfFormatter())
        Dim fd As FontDef = New FontDef(rptReport, "Verdana")
        Dim fp As FontProp = New FontPropMM(fd, 25)

        Dim page As Page = New Page(rptReport)

        page.AddCB_MM(80, 80, New RepString(fp, "Test"))

        rptReport.Save("test.pdf")
End Sub

and I keep getting this error when I try to run it:
"Value cannot be null. Parameter name: stream" The debugger is showing it on the rptreport.save line.

Here's the full exception detail:
