CorelDraw Graphics Suite 8: Does anyone know of a discrepancy glitch in measurement units: points, in the new edition?

Hi, all. I've been trying to upload a client's color dust jacket image files to Lulu for days now and despite checking and rechecking the overall specs according to their posted specs, the "postscript points measurements" of the files I'm sending are coming in too large by sometimes more than twelve points. I use a 24" hi-rez monitor and check dimensions in CorelDraw at 300% to make sure. The files are right on spec in my machine, but rejected by their autovetter. Anyone have similar issues? At first, I tried a simple publish to pdf in vector & bitmaps as always, then I exported the entire document to 300 dpi CMYK then to pdf, but still NG. Should I try Adobe Illustrator or some other format to pdf?
