Remove all instances of the PDFMaker.dot and PDFMaker.xla files from \Program Files\Microsoft Office\Office version/Startup folder and reinstall PDFMaker using the Help > Detect and Repair menu option in Acrobat.
So, apparently Adobe isn't talking on this at all..... I have three computers with the same issue, I am about two steps from stopping all updates to Adobe and using some other form of similar software. I can get fine PDFCreators from several sites around the world, and they all work fine. Acrobat 8 Pro cost us some money, and has some great features, but if we can't get this resolved, we will downgrade and begin looking elsewhere.
