Just got a 720 at costco yesterday. Installed software, everything went fine. Created account, devices, activities.... all good. Update device - stuck at 0%. Tried the web interface, gets about 92 bytes of the file (update.ezhex - yea like its easy :-)
and hangs there forever (actually timed out overnight). Disabled firewall, AVG, popup blockers, put members.harmonyremote.com in my trusted site list.... nothing.

Rebooted 720 in safe mode, reinstalled firmware (successfully I might add), tried again, same thing. I am convinced itis not actually the device but Logitech software and web site crashing into something on my machine - Dual Core, 2 GB Mem, 500GB disk, IE 7 - Hmmm I wonder - tried it on my laptop - IE 6 - SAME THING!

Called Logitech support - WORTHLESS!!!

Can anyone help?

Thanks
