Lexmark c530dn Fineprint

My new Lexmark C530DN does duplex printing fine normally, however
when I try to do booklet printing from .PDF using Fineprint the back
page always comes out upside down. Ive used the wizard, Ive tried all
the flip options ,none singally ,and both, cutting down trees in the
process . and still no joy.

Its got to be simple but I just cant get it. HELP Required

Thanks
