Windows 7

Can anyone help me jailbreak myappletv so I can install the beta that I paid for? I am using snowbreeze 2.1. The ipsw build seems to go ok. I plug in the atv, reboot, then go into DFU. Then itunes launches, I select option + 'restore' and choose the new file on my desktop created by snowbreeze. iTunes starts to install it and then end in the error. "The Apple TV 'Apple TV' could not be restored. An unknown error occured(3194). Anybody have an idea how to get passed this?

I tihnk this error occurs when you try to downgrade.

Are you using Tiny Umbrella? Which software do you have on your ATV, and what is the filename of the Custom Restore IPSW you built?
