Stuck in iTunes Restore

Tried jailbreaking on a Mac, didn’t get too far.  On Windows I get the ipsw made, but when

the iTunes restore script is running, it does just that , forever…

Is this a common problem and any solutions?

Nevermind, tried one more time and got it.

i have the same problem on a windows machine. I updated on the last atv update and get a windows then black screen. So I am trying to restore with no luck I have tried this about 10 times with no luck it just keeps running, i let it run overnight nothing, please help
