My world is corrupt help! How to recover world?

[TTG]

ive been running an FTB server on my Win7 machine flawlessly for a month now.

Yesterday, it was crashing on bootup. I fixed it by generating a new world, however....... my old world is corrupt,
Is there any way to recover all of that world?

The latest thing I had done in the original world is craft quantum leggings (if that info helps)

Thanks in Advance,
TTG

Here's the crash report from my original world............

Try using MCEdit to copy buildings and important machine set ups to a new world.

Edit: If one of your world files is in fact corrupt, it is not easily repaired and might as well be trashed.
