Hyperlinks have stopped working in Acrobat 9 pro

Question

Hi all,
I have been using acrobat 9 pro for quite some time now, in conjunction with Microsoft Office 2007, specifically Excel 2007.
I have been using Excel 2007 to create my reports which have several worksheets. The first worksheet is a simple cover page and the second a worksheet with data relating to the next "x" amount of worksheets.
On this second worksheet, I have included several hyperlinks which point to the other "x" worksheets within the workbook as a whole.  The other worksheets then have a hyperlink which takes them back to the data (second) worksheet.  Sort of like a homepage pointing to locations, with a "home button" on each subsequent page.
Once the reports were finished, I then clicked the PDF maker button, and added "all worksheets" or "entire workbook" whichever took my fancy at the time to create the PDF.  This hhas been working perfectly for over a year, however, last month this stopped working.
Previously when creating the PDF file, being a really boring nerd i decided to click the "show progress" button which showed every step of the conversion process from "performing post processing" to "scanning for hyperlinks" etc.  Now when I click the "show progress" button, all that appears is "performing post processing," the scanning for hyperlinks has completely disappeared.
I have checked the settings, in case they had been changed accidentally, however, the "include links" checkbox is ticked.  I have also tried creating several (well all) different formats of the Acrobat PDF from version 4 through to 8, all with the same results.  The text that should be a hyperlink is blue and underlined, but has no link.
If i create a PDF/A format file, the hyperlinks are the same result (blue and underlined) however if you hover over the link text popps up with the address of where the link should point to in the document, eg. "Page 6 XYZ 59 542 NULL."
I imagine the "NULL" part has something to do with this feature not working.
My current version of Acrobat is 9.1.2 and I am wondering if the update from 9.0 is what has caused this, and if so, does anyone have a way of making the hyperlinks work.

The source of the problem (Excel internal Hyperlinks no longer convert to PDF file) has been FOUND...check for the installation of "Microsoft Excel 2007 Security Update (KB969682)".  The Knowledge Base Article, dated June 9, 2009, http://support.microsoft.com/kb/969682 actually lists one of the two issues we started to notice at the end of June / early July.  The recent Adobe Acrobat 9.1.2 update was more than likely just coincidentally released at about the same time as Microsoft's KB969682 security update for Excel 2007.
We uninstalled the "Microsoft Excel 2007 Security Update (KB969682)" update from our Windows XP workstations, and the Adobe PDFMaker Add-In 9.1.2 works fine now...no more distorted graphics and Excel Hyperlinks are now back into the PDF files!
