I am using ArcMap 10.2.2. When I go to "Add Data From ArcGIS Online" and click "add"on something, nothing happens. It has always worked for me in the past, but for the last two weeks, it hasn't. The ArcGIS online window closes, but nothing is added to my map. I am signed in to ArcGIS online, and I have tried different datasets, including ones that I know have worked for me before. I don't have any problem adding basemaps or web map services. Has anyone seen this, or does anyone have an idea on how to fix it?
