Hi all, I'm having some problems. I downloaded the World of Minecraft client, placed minecraft.jar in the /lib sub-directory, and I'm using this script, but I'm still getting the "Could not find main class: Main. Program will now exit." error. I've searched all over the place, I've done a chmod +x on minecraft.jar. I don't know what else to do. Can someone help me figure out why I can't run this?
