Outdated Server

[yottabyte]

Activating melvin mode....

Actually, if you look in the Minecraft terms of use you see this:

The One Major Rule

Do not distribute anything we've made. This includes, but not limited to, the client or the server software for the game. This also includes modified versions of anything we've made.

In order to ensure integrity of the game, we need all game downloads to come from a single central source: us. We hope you understand. It's also important for us that 3rd party tools/services don't seem "too official" as we can't guarantee their quality. If you wish to make something pertaining to anything we've made we're humbled, but please make sure that it can't be interpreted as being official.

Anyway, glad it worked out. Remember to do backups of minecraft.jar.
