PDFMaker (Acrobat XI) add-in causes Word 2010 and Word 2013 to crash

Hello. I'm having an issue with Acrobat XI and Word 2010 and Word 2013. Whenever I try to create a PDF using the Acrobat tab on the ribbon, I get a message that Word has stopped working.

I have installed the updates for Acrobat.

This is the error log from Microsoft Word 2010:
