Fixed.
Updox support did call me today and were helpful. I took 3 days but eventually they came through.
It turns out I was NOT the account holder. I had switched that to my office manager in the past. Once I made myself the account holder, I could see the "AC user mapping" option under admin in the updox utility.
AC Auth service is located in the server / computer that hosts AC. I started the service easily once I figured out where to look.
So now when I press the secure button it sends me to updox web 2.0 version.
Can you edit documents in updox web 2.0 like you could in the java version? I could not find a way to do that.
Thanks for all your help.
