Hello. I actually called in to Adobe support. The tech on the phone solved my issue. He logged into my machine and installed an update. The Creative Cload app said I was up to date, but apparently I wasn't. I am sorry that I do not have the link to the file he installed, but the name of the file is: AcrobatUpd11001.msp
Anyhow, after installing, we went back into Word and still had to check the box shown above to reenable the add in. But now it works! Thanks Adobe support!
When you post, do not expect an immediate answer. We users do not live on this site and check periodically. However, one of us is often around. I was considering replying about doing the updates when I got to your second post. Actually 11.0.01 is even old. You should be able to do updates from the Help menu in Acrobat or download them from http://www.adobe.com/support/downloads/product.jsp?product=1&platform=Windows. The updates generally have to be installed in order (most are not cummulative).
WORD 2013 was released after Acrobat 11.0.0, requiring the updates for Acrobat to properly operate. Even if a beta was available, Adobe does not generally target the beta for updates since they are often totally different from the final release, wasting a lot of programming time on the part of Adobe.
It's not a matter of expecting an immediate answer. I just wanted to reply back right away to let people know that my problem was solved, and more importantly to post the solution to help anyone else out in the same situation. I post on many forums and you see lots of people ask questions, then either disappear or come back and say "I solved my problem" without saying how they solved it.
I use Adobe Creative Cloud. It said my Acrobat was up to date. So, as far as I knew, there were no further updates. Thanks for the link though.
That is fine. I was just trying to give you a heads up, particularly since calling Adobe usually involves $$ and may not produce an answer. That is why a lot of folks end up on the forums. The disadvantage of the forums is that you have to wait until someone checks in that is aware of a possible solution. In many cases, you might find the solution to be better than what you obtain from support.
In any case, glad you found a solution.
