HELP PLZ!!!!!!!!!!! Help with my ipod touch ??? I am really Scared !!!?

I've had something happen like this to my regular ipod. Do you have the most recent itunes and Quicktime downloaded to your computer? That could be the problem. Then again on some computers the newest Quicktime for some reason doesn't work with the new itunes. So download the new itunes. Erase the new Quicktime and download the old one which I think is number 3 not 100% sure. That might work. Hope this helps.
