My Ipod Touch was messing up so i decided to force restore it. It was in the process of restoring and some of my friends came over so I unplugged it from my Macbook and left it on. Well when I came back Itunes was stuck. It had a progress bar in a new window that said "preparing ipod for restore" and has been like that for 3 days. I can't quit the application or turn off my computer. I even let my computer lose all the battery power and shut down, but when I turned the computer back on Itunes was still stuck. Please, I need help!
