I'm new, so hi everybody

Yesterday I was watching a movie on my new setup, when suddenly the message 3 appeared, thank you Cinavia... So googling made me find this site, so I registered immediatly!
I think I get the idea what you guys do with the custom firmwares, so I want it on my machine too.
So far I changed the DNS, but I got the error 800: no resource error

My model and firmware is:
HT-E6730Series_ZF (The box says E6750W though...)
HTB-E5500WWB-1019.3
Is there a place where I can download the firmware to a USB drive?
I really hope you guys can help me... If not, I think I wasted a lot of money on the rig and on the "Movie Fix 2.0" methode that works, but it's such a hassle to do with each movie I want to see...
So thanks in advance for every good samaritan who tries to help!
