Sorry guys,
suddenly I got a strange problem. My Yappari application is always crashing after logging in. If new pending messages are present, it downloads them and then crashes while keeping the icon in the status bar as active but not working if tapped. If I check Account Info I can read that Service Expiration is July 2nd 2015, Status is Active and Service Type is free. Now I wonder if I should pay Whatsapp to get service.
