OK, I'm stumped. I have a HK-TC30 and Harmony 620. My Harmony is updating fine but my HK-TC30 has stopped working. I get the error "Error Sending Data" message. I have disabled firewall software, etc (non of this has changed BTW since it last worked). I can't remember if I ever tried it after I upgraded to the Linksys Wireless N router. I've logged into the router and I don't see where anything is being blocked but I could be wrong. Any techies out there who might have ran into this?
