I've been using ArcGIS Earth for a couple months and it has performed great. Today though I can't use it without it crashing. Adding different data sources (Scene services, KML) that I've added before or just navigating cause it to crash. I've tried uninstalling it, reinstalling it, repairing the install. I've tried going back to version 1.0 and I've also tried changing the 3D settings for my preferred graphics processor in my NVIDIA Control Panel. None of this has resolved the crashing issue. Does anyone have any suggestions on troubleshooting this type of problem?
