I have installed ArcGIS Earth beta few months ago.
When I first tried it, everything seemed ok. Recently, when I launch it I can't see anything but the interference, meaning no globe with basemap is displayed in the Viewer. All the other buttons (e.g. add data) seem to work without problems. Could it be due to my graphic card? As far as I understand, my Ultrabook has an Intel(R) HD Graphics 4400.
