OK, the Chat thing is working now. I can get to a channel. But right after I typed something it said "Disconnected." When I tried to connect again, it said that my nickname is already in use.
So I can only get on for a few seconds and then I have to wait. And then I can get on for a few seconds, and then I have to wait again. And so on...
Sorry...
Edit: Is it because I have Windows Vista, maybe. Because it says.
