Cannot view placed art in a PDF in an email

Question

When I get a PDF as an attachment--be it in Entourage 2004 or Mail--I can't view what I assume to be placed art in a PDF. It doesn't show up in either program's preview pane, or if I download it to the hard drive and try to view it in Preview or Adobe Reader (version 8 or 9).
However, if I forward that email and/or file to colleague's--PC or Mac, doesn't matter--they can view it in those same programs, in all the ways described above.
Clearly, something is wrong with my Mac, I just don't know what

Hi, Have you done any Disk or OS maintenance?
If not, Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
