After I checked the Day/Night overlay feature, I am unable to see any maps. I've deleted Browsing history and rebooted and all I see under Maps is a solid blue screen where the map should be. The green progress indicator stops about 1/3 and never continues. I am using Win 7 SP1. I am on a work computer that will not let me access the registry. What can I do to restore to normal operation?

Thanks in advance,
