Over the past hour I've been trying to send messages through whatsapp. (I have a lumia 520.) But when i click on the name, the app hangs and the chat doesn't open. I've tried locking the screen and trying again, turning off my phone. Nothing worked. Please help.

reinstall the app. And turn off the restrict background data usage in data sense settings.
