Electric Engines caused a problem in the world, making it crash. The only way to fix this was to delete the mod from Tekkit Lite. Re-Installing the mod causes the same crash problem. If you really want Electric Engines back, I would recommend installing Forestry into your client. Forestry brings its own Electric Engines into the game, that you can upgrade to be  more efficient. But a better solution would be to use the multi-block Power converters.
