IPod touch Downgrade Problem Need Help

I was tring to upgrade my jail broken ipod touch 1.1.1 to 1.1.2
That went ok but jail breaker installer was not there. So i went to downgrade to 1.1.1 but during the process, somthing went wrong. The computer said it was done and the touch had the plug into the itunes picture so, i unplugged and plugged it. But nothing happened and how it is stuck in that screen. I am running vista

Any help, please?? I need my ipod touch

I restarted my computer then plugged in my ipod touch and the problem was solved.
