Hello there! At first glance, it appears to be a problem related to Java. Are you able to press any buttons? If possible, try to update your Java to the latest version and make sure you are giving the chat permission to be executed (though, seeing as how it shows the chat partly, I don't think that is the problem). You could also try a standalone software or an alternative site to access the chat, such as Mibbit (online), Quassel (standalone) or Chatzilla (a Firefox extension). If you decide to use any of those and need help setting them up, feel free to give me a nudge!
