I knew about this Bing Map change and possibly having to get a Bing Maps Key in order to add Bing Maps as a base map, however you could still access Bing Maps via the "Add Data from ArcGIS On-line". Is this option of access to Bing Maps no longer available also?

I've done all of these steps and had Bing maps working with my keys for about 6 month and now all the sudden they aren't working. The keys are still valid and nothing has changed as far as software. My co-worker has the exact same set up as me and they work for her. Can't figure out why it's not working for me... Bing Maps broken source fix
Well I figured it out. I was not connected to ArcGIS Online in my system tray. Kind of disappointed this is a requirement to use them...
