ForgeModLoader state engine has become corrupted

[Squirrel Mclovin]

I was playing FTB Ultimate 147 when power went out. Come to find out my laptop battery doesn't work (one is on order now) and my computer instantly shut off. Now, when I try to load the world, I get the "ForgeModLoader state engine has become corrupted...critical error...not recoverable...engine is invalid..." etc....etc... It was about this time that the Windows Installation Service stopped working as well.

All other worlds in other ModPacks work good, and my FTB Ult creative world works too.

Ive tried disabling and enabling several mods (most notably Wireless Redstone because I saw worked in one post) and changing Java parameters. I havent been able to find a fix and have gone so far as to completely reinstall Windows 7 (this fixed the Installer Service problem), reloaded Vanilla Minecraft, Java, FTB Launcher and Modpack, and tried to correct the problem through MultiMC and nothing has worked.

Any help will be greatly appreciated! Thank you!

Unfortunately, your world got corrupted. It is really hard to fix these sorts of problems. The easy way is to delete it and make another.
The hard way that might/might not work can be found here: http://forums.bukkit.org/threads/java-util-zip-zipexception-not-in-gzip-format-world-corrupt.31409/.
Note, that way to fix world corruption after blackout was only tested on Bukkit servers. Backup your current save and try that.

I tried this and it still doesn't work. I am not entirely sure I did it correctly though... I know some of the files and their locations but overall I'm not to familiar with that stuff. I'll keep trying, at least until the 1.6 modpacks come out; hopefully that will be soon. I've found myself with a lot of free time since the world corrupted LOL

Thank you for the help!!
