Messages app won't open
I tried opening Messages today and it would not open. Earlier today I was playing a game and then my iPod suddenly restarted (I saw the Apple logo) and then it was back to normal. I didn't try the Messages app until when I noticed that it wouldn't open.
By "not open", I mean I would click on it, load, then a black screen would appear before it would close out.
I turned off iMessages (and now can't turn it back on). I can send texts/iMessages through Siri and receive them. All of the other apps open and close fine.
Here is a video of the issue. http://youtu.be/Ngwer5cqTb0
