Ok well there are a few things here that could be the problem.
Are you saying Yes for Seas0nPass to run the iTunes script to automatically restore or are you attempting to restore just from inside of iTunes?
If you are attempting to restore from within iTunes you need to click Shift+Restore to bring up a dialog box that will allow you to select the IPSW that Seas0nPass created. Now you cannot just restore the IPSW without putting the device into Pwn DFU mode. If you are using Windows you can download and run a program called iREB (once running click the Apple TV 2 button and this will upload the final stage to allow the custom IPSW to be restored).
So what I need to know is what type of computer are you using, Windows or MAC?
If you are allowing Seas0nPass script to run or not.
