How come my iMessages aren't sending anymore I have a iPod touch 5th gen. It was working and then like 5 minutes later it would not send any messages it always said not delivered even when I press retry and it doesn't send at all I even updated my iOS.

How come my iMessages aren't sending anymore I have a iPod touch 5th gen. It was working and then like 5 minutes later it would not send any messages it always said not delivered even when I press retry and it doesn't send at all I even updated my iOS to iOS 7.04 to see if it will send my iMessages but it won't. I tried to send a message to anyone but it won't work even when before I would be able to send messages but something weird happened that made my messages not delivered. Is there any way I change fix it?
