Okay, I did every step correctly. Putting the minecraft jar into the lib, and double clicking the bat. It then asks for my username and password for the game. I do that, I choose a server, and hit join. All I get is a white screen the has Switch, Reload, Screen-shot, Dump Level, and a check box for enabling hacks. That tells me that I'm at the right place, but the screen stays white. It doesn't connect. I'm on an XP, can you help me?
