Details of the issue:

So recently the Direwolf20 pack on FTB recieved an update which i of course did, re added my old mods that i had used previously which worked perfectly, however after i re-added them into the new update when ever I try loading my old world it crashes before I can actually get into game, though I can create new worlds perfectly fine.
This is what happens -

I think everyone needs a little bit more information to help you with this...

If you received a crash log from this, post it, or, if this was one of those crashes that doesn't give a crash log, post the console log.
Giving a list of the mods you added might help everyone help you as well.

Good luck!

The mods I added post update were; Ars Magica 2, AnimationAPI, Aroma1997's Dimensional World, extraTiC, a updated Forge Multipart, Harcore Ender Expansion, IguanaTinkerTweaks, Malisiscore/doors, Metallurgy core, metallurgy, optifine, powerUtils,

Though unless I waned half my world deleted/replaced I had to add them all back anyway due to modded block placment and generation, and also these all worked perfectly before the 1.7 update.

I believe it is a conflict between Forestry and HEE, but thats all the info thats really there, besides the fact that its one of forestry's ores

You may have to update other mods as well.
