Recently, my iPod began to act up. It's a fourth generation one, by the way. Basically, one day the folder with exclamation point icon came up on my iPod. So, thinking that for whatever reason it couldn't read the files, I thought that I could simply plug it into my Windows computer. Anyway, upon plugging it in via USB, but iTunes couldn't recognize it. My computer could, but iTunes couldn't. I then reinstalled iTunes (newest version). No change at all. Next, I tried to reinstall the iPod Updater. For some reason, it didn't want to work. So, I downloaded the latest version from apple.com, and it ran through half of it, until it finally said, "1628 Failed to complete installation." I have no idea what could be stopping it from installing. Any suggestions on what could fix either my iPod or the iPod Updater.
