no worries, sorry it didnt work. One more idea actually. You need acrobat distiller fro this, but pretty sure you will have this if you have CS4. export all the pages but as eps not pdf. This should save it as single pages. After this, open up distiller and drag all the eps into it. Think this should work. It involves distiller so still a bit of a process, but hopefully will work.
All the best.
