Java has done its usual thing of updating and then throwing a strop when you try to get into the chat room.
I have spent most of the day fighting with Java until finally coming up with a solution....
So Java WILL update for you soon and you probably will not be able to get into the chat room, here is how to solve it.......
1... Bring up the Control panel on your computer
2... Search for Java in the search bar and then click on to Java when it comes up.
3....Click on to the security Tab and then 'Edit site list'
4..... Type http://www.nomorepanic.co.uk in the box and then click add.
5..... It will then warn you that you shouldn't add NMP but just click continue
6..... Remember to click Apply before you close the window
And that should be it.......simples
