I wanted the Media Center, and other features. I don't just use archicad you see, I want to do other things. Even though it may have been foolish.
Anyway - I think I worked around the problem - Install Adobe Acrobat 8, then just "print" your documents to the pdf printer, select the scale, and use the pdf printer to create your pdf's, this gives you the high resolution exports we have come to experct from Archicad.
Everything else in Archicad 10 seems to work fantastically well. Once graphisoft sort out that PDF converter in the publisher we are away.
cheers
