mike, try this:"Error 3194 seems to be triggered when unsigned firmware is used, often during an iOS downgrade or even during some restores. Here’s how to resolve the error: Fix Error 3194 The fix is the same regardless of what operating system you are using: Quit iTunes Locate your hosts file, in Mac OS X this is /etc/hosts and in Windows this is c:\windows\system32\drivers\etc\hosts Open the hosts file with Administrator privileges Add the following lines to the very bottom of the hosts file: 18.104.22.168 gs.apple.com Connect your iPhone to the computer Launch iTunes Put the iPhone/iPad/iPod into DFU mode by turning the phone off and then holding down the sleep and power button for 10 seconds, then release the power button but hold onto the home button until iTunes tells you that the device is now in recover mode Use the iTunes Restore feature as usual with the iOS device Once your iOS update is finished, remove the “22.214.171.124 gs.apple.com” line from your hosts file again so that iTunes can properly update as usual." from [http://osxdaily.com/2010/12/06/error-3194-fix-for-itunes/|here.] Also, if you are using Windows, disabled the firewall. hope this helps, good luck.
