PDFArchitect Merge 2 pdf files produces white square

When merging 2 PDF Files (each of them containing only 1 page) the result is OK with PDFArchitect. But when opening the file with Adobe Reader V10.1.5 I obtained 2 pages containing only a white square.    
System Windows 8 64bits, PDFCreator (+Architect) V1.6.2 just installed

Hi,

have you tried using a third reader (like Foxit) to ensure it´s not a adobe issue?

regards,

Robin

I can’t do more test because temporary I have no access to my PC (returned to SAV) but I suspect some issue with the PDF generator. Sometimes I generate PDF files with the Integrated generator in the print module of Google chrome (maintain active links) and sometimes with PDFCreator.

And in other circonstances, I had issue with PDF generated with Google Chrome.
I will check this with different PDF files.
