Man, these Logitech Revue's are starting to have major problems. I just began using a hardly-used Revue a few months ago, after having "worn out" my first one. The other day, I did a factory reset. Now I'm getting a Google Talk Authentication Failed message. What that means is that the Play Store isn't accessible, so no ES File Explorer. Maybe there's an APK for it. I've done a second factory reset, but the problem remains. My Chromebox won't be received for a few months. I'll make do in the meanwhile.
