Populating pdf form fields and saving this pdf page appended to a larger pdf document

I have a pdf form with 4 fields to be populated with data. This file is saved into a memory stream and appended to a larger pdf document. It is deployed into IIS7 environment using .NET 4.0. This works in my development environment. The problem is that the form field data disappears when I deploy it to the server. 

My code that works in development environments is at follows:

            If IO.File.Exists(templateFile) Then
                Dim appendDocStream As IO.Stream = New IO.MemoryStream
                Dim appendDoc As PdfLoadedDocument = New PdfLoadedDocument(templateFile)
                    ' Load the form from the loaded document.
                    Dim form As PdfLoadedForm = appendDoc.Form
                    ' Load the form field collections from the form.
                    Dim field As New PdfLoadedFormFieldCollection(form)
                    Dim thisField As PdfLoadedField = Nothing
                    Dim fieldValue As String = String.Empty
                    ' TryGetField Method.
                    If field.TryGetField("Date", thisField) Then
                        TryCast(thisField, PdfLoadedTextBoxField).Text = "20 Sep 2013"
                    End If
                    If field.TryGetField("Client", thisField) Then
                        TryCast(thisField, PdfLoadedTextBoxField).Text = "Test Name"
                    End If
                    If field.TryGetField("Project", thisField) Then
                        TryCast(thisField, PdfLoadedTextBoxField).Text = "Test AddressText"
                    End If
                    If field.TryGetField("DrawingNo", thisField) Then
                        TryCast(thisField, PdfLoadedTextBoxField).Text = "TestDrawing 001"
                    End If
                    'form.Flatten = True ' ' NOTE this line deletes the populated field data
                    appendDoc = New PdfLoadedDocument(appendDocStream)
                Catch ex As Exception
                    ErrorHandler.LogMsg(templateFile & " is not a pdf form")
                End Try
            End If

Does anyone have any ideas on how to improve the above to solve problem on server?
