Hi, I had installed ArcGIS Maps for Adobe CC on Adobe Illustrator CC 2017 - it was working fine as far as I could tell.
Adobe released their CC 2018 update, I installed that, then in Illustrator I go to: Window/ Extensions/ > but all that is available is "Libraries"

Am I missing something?
-Is it now somewhere else?
-Or do I need to reinstall the extension?
Which brings me to my next point; I get this message when I try to click on the extension in the Adobe Add-ons:

So it appears that at some point between CC 2017 update and CC 2018 ArcGIS update, I've lost the extension.
-Any ideas as to what the issue could be?
