The Elevation Profile Add-In service appears to be down. It is not generating any elevation profiles. I've tested it on maps where the add-in previously worked and it is no longer functioning. It only displays a blank pop-up when I run it. This can be the result when there are too many vertices, but that is not the case this time.
This is referring to the add-in described at http://www.arcgis.com/home/item.html?id=e7d97dd9c005472a8ea887db8eb1366a
