I can't get rid of iTunes error 3194 and i've tried everything?

I'm bored with ios 6 and i want to get ios 7 back. But every time i click update or restore an error message pops up and says something went wrong, error 3194. I've tried the hosts file stuff multiple times but it still doesn't work. I got my UDID registered but that didn't do anything. Still geting the 3194… Please help i'm all out of options
