I have a customer supplied InDesign CS3 PDF, 184 pages all black text. I impose into 32 page sheet wise signatures in Indy CS2 and it will not export to PDF. I get no real error just "File failed to export to PDF". I also tried just a few pages in CS2 at page size (6.5 x 9.5) and I get the same thing. Odd thing is it will export from CS3 and I also can export a Eps's from CS2 or write a postscript file and then distill. Just seems odd that it won't export. Did Adobe do something to CS3 PDF export to make those PDF's incompatible with earlier versions of Indy? I also tried dropping the PDF into CS and it just crashes when I attempt to export to PDF.
