Hello!

I'm using the free version online at the multiplayer mode and as soon as I'm trying to join a server (of which I have an URL) the java module seems to "die" after the logo and the applet change message flashes by. It just refuses to connect and stays black with no loading whatsoever. No servers seem to work at all. It started last night but I managed to connect to some servers then anyhow. Now it's not letting me connect anywhere. It really seems to be java which is faulty.

I've tried:
Restarting the computer
Changing the browser
Updating java
Clearing cookies
Using different java versions
Downloading a fix with additional java files

...but nothing seems to work. There is nothing wrong with the network connection either.
I'm using windows 7 64-bit if that is helpful.

What should I do? Any help is appreciated!
Thanks.
