@ The Alien, please let us know if Xara can fix this for you as I had the same PDF export problem on Designer Pro 12 and never did get it sorted.
All my customers send me PDFs and I have to send them back as PDFs so it was something I couldn't use XARA without.
I stopped using Designer Pro from then onwards because of it, but maybe could be coaxed back if it is fixable (to UK Xara, not Magix).
