So I just downloaded the 1.5.9 World of Minecraft client, and I moved the minecraft.jar into the lib folder, but when I run run.bat, the command box stops at "Starting java from "C:\Program Files\Java\jre6\bin\java.exe"

I am running Windows XP, and have the latest non-/indev/ version of the Minecraft Client. Am I doing something wrong, or is it a glitch with the client itself?

EDIT: forgot to mention, it has been stuck at that screen for about 15 minutes
