Converting Word 2007 to PDF

I am not totally sure if this is the right forum since I suspect the solution
lies in an add-in or some such obscure place, but, insight comes from all
places.

I have a User in my area Who has been trying to Print to PDF ,various word
documents ( Word 2007 which were originally Word 2003) that have Excel (
Originally 2003, but I ASSUME get converted to 2007) Embeds.
The Problem is that where-ever the Excel embed in Word 2007 is( After
printing to PDF), the PDF displays that area as Black.Its as if the section
suddenly becomes hidden.

I checked the Excel embeds, and no Links to outside files have been made (
I thought that the Black was caused by the PDF file not finding any link).
Anyways, in both Standard and Pro Testing of this Issue, using the 8.1.1
versions of Acrobat, I then Click on Examine Document, and "Metadata",
"Hidden text" and "Deleted hidden Page and Image context" are checked.

I then Click on Preview on Acrobat, and I was amazed to see that the Excel
embeds had indeed converted over, but as hidden text. I don't know if this
occurs because of Acrobat 8.1.1 or because of Word 2007.

If I change the Radio button in Preview (in Acrobat) to "Show Both Hidden
and Visible Text", then it shows the full document in preview.
My hope is that I can somehow setup Adobe Acrobat, and/or Word so that the
Hidden elements will display. Most of the users who need this to work don't
have a whole lot of patience with too many "steps".

To date I had pre-supposed that the issue lay in Acrobat, but since I am
trying to come at this problem from many angles, I am supposing at the
moment, that maybe word is the issue, since when I use the Informatik driver,
many of these documents will convert. Even if I use the PDF/XPS Publish to
add-in, the items convert, but the documents radically change, and since the
Documents are predominantly Legal Documents, they have to follow specific
formating, and I can't follow that route.
In essence, Acrobat does convert the Documents properly, its just that
certain key parts that happen to be Embedded Excel elements are displayed as
Black space.

If this is the wrong forum for this question and you know of a better one,
please advise me.
