Is 8.1 Certified to work with VISTA or NOT

Sounds as though Microsoft Office automatically disabled your PDFMaker macros when you updated to 8.1. Here is how you can manage your Disabled Items list in a Microsoft Office application:
1. Open the Microsoft Office application (Word, Excel, Publisher).
2. Choose Help > About [the application name].
3. Click Disabled Items.
4. Select Adobe PDF from the list, and clickEnable.
5. Quit the Microsoft Office application, and then restart it.

If the error message continues to appear after you enable Adobe PDF, then check the security level for macros in Word:
1. Choose Tools > Macro > Security.
2. In the Security dialog, click the Security tab.
3. Choose Medium or High.
4. Do one of the following:

-- If you chose Medium, then click OK.
-- If you chose High, then continue with steps 5 through 7.

5. Click the Trusted Publishers tab.
6. Check Trust all installed add-ins and templates.
7. Click OK.

PDFMaker and the right-click context menu should function again.

I am having selected Excel 2007 printing pdf problems. I get the Error 1310 but a different file: c:config.msi\38efd03.rbf is missing. The result is some Excel programs print one blank page from a 3 page spreadsheet.

Please advise.

Check your dpi settings in the Page Setup and make sure they're the same for all your pages.
