I can save my Word 2007 in several formats.  docx works just fine.  Also save as PDF or XPF works fine.  However, if I select Acrobat PDF, I get the message "Word experienced a serious problem with the 'acrobat pdfmaker office com addin', add-in. If you have seen this message multiple times, you should disable this add-in and check to see if an update is available. Do you want to disable this add-in?  Yes No

Also, if I try to use Adobe Acrobat to create a PDF file from my saved Word 2007 docx document, I get the message "The Security level is set to High. Please run the application which created this document, in the "Security Warning" dialog select the check box "Always trust macros from this source" and enable macros created by Adobe Systems Inc."

What do I need to do in those two cases?
