When I attempt to customize the controller keys, I immediately receive this message. Revue is on latest firmware, fresh off a factory reset. It is connected via ethernet and wireless. Device works fine otherwise (youtube streams, browser works, can log into google services, download apps, etc) Ultimately my goal is to set up custom keys so I can change the channels on the television by having it learn the IR commands, but this is a complete roadblock to that. The best I can do right now is not even use the keyboard controller and instead use the Google TV app on my Android tablet to 'switch input' from HDMI1 to "TV" which will bring it to channel 2.1. But I can't change the channels up to any other channel or back down to HDMI1 (though I can use 'switch input' from the Google TV app to get back to HDMI1). I don't have a set-top box setup with the revue, as I get my regular TV over-the-air from a digital antenna screwed into the coax connection. Any ideas?
