Two possibilities come to mind:

1.  The Acrobat templates are not in Word's startup folder.  In Word,
click on Tools | Options | File Locations.  Note the location of Word's
Startup folder.  Close Word.  Open Windows Explorer, find the
PDFMAKER.DOT and PDFMAKERA.DOT files, and copy them to Word's Startup
folder.

2.  In Word, you have Macro Security set to High, which suppresses the
Acrobat toolbar macros.  In Word, click on Tools | Macro | Security |
Trusted Sources tab | check the "Trust all installed add-ins and
templates" box.  Before you do this, BE SURE YOU TRUST all installed
add-ins and templates.
