Cannot optimize Powerpoint 2008 files using Acrobat Pro

[Eurythenes]

Version: 2008
Operating System: Mac OS X 10.5 (Leopard)
Processor: Intel

When I use Adobe Acrobat Pro (v9) to optimize pdf files of my Powerpoint 2008 presentations i get the following error message:

"an error was encountered while processing images"

I can optimize pdf files created on Word 2008 and Powerpoint 2004. PPT or PPTX files converted to pdf files on Powerpoint 2008 both get the same error message.

Is there a fix for this?

Update:
The good people at adobe told me that this was a problem with Powerpoint 2008.

The (not so good) people at Microsoft told me that this is a problem with Adobe.

The problem only occurs on pdf files made with Powerpoint 2008, pdf files created using PowerPoint 2004, Keynote, MS Word, etc. all function fine with Adobe Acrobat Pro
