I downloaded ArcGIS earth and at the first zoom in action all the imagery tiles of the base map were a mess. like a puzzle that a little boy messed up.
We are seeing a couple of users with this issue. Is it possible you are going through a proxy or some other config that is filtering your web requests?
I just downloaded ESRI Earth and am having the same issue. I am not using a proxy server. The only thing that is out of the ordinary, setting-wise, is that I am behind a firewall.
