First blush I don't think it is Bolt related... I'd reboot the router for starters. Also try pinging the "blocked" domains from your PC and see if they are reachable (hopefully they haven't configured the server(s) to not answer so it's a valid test). You can go from there based on the results...I unplugged and connected wirelessly and now the Bolt works normally, playing all recordings just fine. If I plug the Ethernet cable back in, it shows the blocked message again. (The wireless and wired connection are using the same ip address).
Wondering if anyone out there knows a way to clear the cookies off the Bolt without doing a full reset.
