You can MODI FILE from VFP to take a look if you like, but you may not like what you see. :-)

Acrobat says that this file was created by Acrobat Distiller, version 6.0. There might be some kind of feature in there not supported by the current version of iSED. (I got a message when loading it into the full Acrobat 5.0 that something in the file is not supported by my version of Acrobat.)
