In-game crash when entering Rocket.

I`m using 1.6.4 with Forge 9.11.1.965, no other mods installed(except Forge Multipart),Micdoodle8 Core 2.0.8.908.I`m using the latest 4Space already compiled version(with the Galaticraft Core already integrated,tried it with the un-integrated version also).Whenever i enter a Rocket it crashes my game.
