Well and here I thought it was just me!

I'm getting the same Java error which is maddening, have contacted customer support via email - no response. I called them and spoke to a chirpy CSR, probably in Bangalore, be prepared to go through all the inane stuff, turn off the fire wall, disable pop up blockers, use IE, reboot windows, reinstall the software, as you patiently try to explain that you really do understand how a PC works and what about this Java error.

You may have some luck not using the java software and going through the browser site;

I also found that instead of updating the remote via the update remote feature if I instead go through the "get support" tab and then "test remote" it will update the remote sans the java error. BUT I'm having no luck with the RF extender, it recognizes it, adds it to the system and then sends everything out via IR, works beutifully but like someone said, $400 for an IR???

Any ideas on that one will be appreciated
