'Unexpected Error' Upon Saving File

Hey! I have a problem with my script. the OnSave method, even though only containing the following code, throws an error. Can anybody think of why?

Protected Overrides Sub OnSave(ByVal input As Document, ByVal output As Stream, ByVal token As SaveConfigToken, ByVal scratchSurface As Surface, ByVal callback As ProgressEventHandler)

        Dim tk As TEXSaveConfigToken = DirectCast(token, TEXSaveConfigToken)
        Using renderArg As RenderArgs = New RenderArgs(New Surface(input.Size))
            input.Render(renderArg, True)
            Dim b As System.Drawing.Bitmap = renderArg.Bitmap.Clone()

           
            Using w As System.IO.BinaryWriter = New System.IO.BinaryWriter(output)
                    w.Write(0)
End Using
End Using
End Sub
