Can not generate a PDF

Can not generate a PDF

I just installed the NetflowAnalyzer V12, I am on the 30 days trial but I notice that I can not generate a PDF, when I click in the PDF icon a bar appears in the top of the page that says "Generating PDF ..." and a very thin progress bar under the text, this tiny bar completes but the PDF never shows up.
There is something missing on the server or in the end station?
