                    {
                        page = writer.GetImportedPage(pdfr, i);
                        cb.AddTemplate(page, PageSize.LETTER.Width / pdfr.GetPageSize(i).Width, 0, 0, PageSize.LETTER.Height / pdfr.GetPageSize(i).Height, 0, 0);
                        doc.NewPage();

Are you able to open the document from your filesystem as normal?

Use BinaryReader and BinaryWriter
example:

C#

Byte[] DocDataStream;

using (FileStream stream = File.Open(OriginalPDFFileName, FileMode.Open))
                    {
                        using (BinaryReader br = new BinaryReader(stream))
                        {
                            DocDataStream = br.ReadBytes((int)stream.Length);
                        }
                    }
// The PDF is now as Byte Array in memory

 using (var filestream = File.OpenWrite(NewPDFFileName))
            {
                BinaryWriter bw = new BinaryWriter(filestream);
                bw.Write(DocDataStream, 0, (int)DocDataStream.Length);
                bw.Close();
            }					
// And your file is rewritten!
