Chat help please
Jenna, I had that exact error as well, here is what I did after I had updated and enabled Java:
it didn't seem to work properly I got error, went back into java control panel (through my system) security tab and realised I had set it to 'very high' earlier. Changed this to recommended 'high' after I closed my browser, so I reopened browser went to chat and got the prompt asking me if I wanted to run the application.
