Title: Help converting a Multiplayer Tekkit map into a Singleplayer Tekkit map

Version: 3.1.2

OS: Win7

Java Version: 1.7.0

Description of Problem:

I run a server and a friend and I were making an adventure/puzzle map for fun, and I'd like to be able to play it in singleplayer, but I can't figure out how to get the buildcraft pipes to show up once I take the world folder and put it into the saves folder. If there's a converter or some simple fix I can do I'd really appreciate it.

I have the same problem-could someone help us out? although when i place new pipes, they appear.
