wpPDF Plus AV in TWPPDFExport.PrintPages

Hi
We have just purchashed a single licence to wpPDF plus to allow us to evaluate it. But we have a show stopper problem. I have previously sent this to 'support@wptools.de' but have not had a reply. Can this forum help?

I am trying to add PDF exporting to wpTools5 But I can not get it to run – I get an AV from WPPDFWP.TWPPDFExport.PrintPages (Line 235, "WPPDFWP.pas")
This line is –
// V2.60 - new way to read page size
w := MulDiv(FSource.Memo._PaintPages[i].WidthTw,WPScreenPixelsPerInch,1440);

I have added this code to our server side letter generation which is build on TWPCustomRtfEdit.

procedure TLTGNEmailLetterIssue.SaveAsPDF(aRte : TWPCustomRtfEdit; aFileName : string);var   pdfExport : TWPPDFExport;begin   try      pdfExport := TWPPDFExport.Create(nil);      try         WPDF_Start(The confidential stuff you sent us );         pdfExport.Source := aRte;         pdfExport.Filename := aFileName;         //pdfExport.FontMode := wpEmbedTrueTypeFonts; // only do this if going to the printery not if emailing as attachment        // pdfExport.Encryption := [wpEncryptFile,wpEnablePrinting];           pdfExport.Print;    // this is line 430      finally         FreeAndNil(pdfExport);      end;      if not FileExists(aFileName) then         raise Exception.Create('Failed to save PDF file ' + aFileName);   except      on e: exception do      begin         e.Message := 'TLTGNEmailLetterIssue.SaveAsPDF' + #13#10 + e.Message;         raise;      end;   end;end;

The stack dump on error is

In debug I get to line 235 WPPDFWP.TWPPDFExport.PrintPages and inspect
w := MulDiv(FSource.Memo._PaintPages[i].WidthTw,WPScreenPixelsPerInch,1440);
I get something for FSource.Memo

In wpdf_inc.inc I have

// This define MUST be enabled. It switches the use of the wPDF DLL on
// If you have wPDF PLUS or the InterNet server edition please
// disable this $define


{$IFNDEF WPDFPLUS}
(*{.$DEFINE INTWPSWITCH} // wPDF Standard: ON  - wPDF PLUS: OFF   *)
{$ENDIF}

What am I doing wrong?

Thanks for that.
It is all looking very good right now.
I expect our evaluation to be complete by the end of the month when we will upgrade to a team lience.
