Problems with pdfEditor.Concatenate demo


I've yet installed Aspose.Pdf.Kit and run the demo for concatenating pdf documents.
The Concatenate method (i.e. pdfEditor.Concatenate(inStream1, inStream2, outStream))
returns false and the output buffer has 0 length.
I've tried the VB one and the C# one on two different PC but got the same result, I've also unzipped the .zip but nothing changed.

Reinstalling previous versions ( and it works.
What is going wrong ?

Thank You

Claudio Mellina
