Since the last update, my Kakao Talk keeps shutting down after the loading screen. What should I do?

If someone texts or calls me I can go to the chat room we share; however, if I try to hit chat--to go back and see all my chat rooms-- it shuts down and I can't get back on unless someone texts me again. Then I can only text the person that texted me. Make sense? Is there a way I can fix this or do I have to wait for the big guys to do something about it?
