Save as pdf/a

Using Delphi to convert some Word documents and I need to save as a pdf/a file, but whenever I try all I got is a blank pdf. If I switch to a normal pdf save format all is fine.

Am I missing something ?

Just tried using the printer using Microsoft Word ( no Delphi anymore ) and all I still got is an empty document.

Here's the log ( notice the error down there, but no description whatsoever ):
