For some reason my computer won't open anything using Java....I can't get into the chat, and I went to the Java website to see if I could just install Java or something, but whenever I click on anything having to do with Java (Chat on this website, Java console on internet tools, download on Java website) it just exits out of my browser, anyone know how to get it working again?

no one knows? come on people, im going through chat withdrawals!

I'd try deleting my temporary internet files -in IE, tools -->internet options, the rest depends on your browser version.

Then open up your java control panel. Usually there's a little tray icon you can right click. If there's not, google it. Delete your cache or temporary internet files there. If that doesn't help, I'd be thumbing through the security settings. Maybe java is blocking you from loading certain content, but it sounds more like a corrupt temporary file issue.

You need to delete and reinstal the whole thing, theres been issues in the past with broken/damaged upgrades. Take it out and reinstall.
