I love ArtsPDF Crackerjack imposition features, but I can not use it on Acrobat XI. and 64bit Windows 7 :( I want to use it, but the new Acrobat version is DebenuPDF Aerialist 11, that contains the imposition parts from previous version. I can find some serials for it, but the old version serial numbers don't work on version 11. Can somebody help me? Thanks.
