Messaging app not showing new messages

[Android Question]

Galaxy Nexus 4, on AT&T
My phone receives new messages because I can see them from my home screen, however the app thread is stuck somewhere around midday yesterday and won't display any messages after that. I've restarted a few times and force stopped the app but nothing has helped. Any tips?

Go to your phone settings, choose Application Manager and select the app.
Tap Clear data and clear cache. That will probably do the trick
