We have updated our MinecraftLauncher.jar with some extra coding, this makes it more stable and reliable, not to mention it fixes a lot of bugs. 

Make sure you read the ReadMe file first! 

1. Copy the .minecraft folder to the directory specified in the ReadMe! file. 

2. launch Minecraft.jar 

3. Pick a username (this is very important for multiplayer) 

4. Play multiplayer online or single player.
