Installed and can't get it to work

Dec 15, 2015 at 2:33 PM
I posted this under issues, but no one has commented yet, so I am hoping discussions will help. I have a file I previously created in Word 2013 using the built-in XML mapping. I am now stuck using Word 2010 and had to download the code (or rather the help desk did if for me as I don't have admin rights). I have followed the instructions, but do not see "Mapping" in the developer tab, nor in the File, Options, Customize Ribbon tab, and it is showing the add-in as Inactive. I had attached a couple of screen shots in the Issues section, but can't do this on the discussion page. Can someone provide me with step-by-step instructions to get this working?
