Problem Crash on startup. Please help!

[Morphiac]

Whenever I start the server, this happens.
I haven't a clue what's causing it, so all help is appreciated.
If it's impossible to fix, is there any way that I can save the world for single player use? It's a pretty special world to me and a friend.

Backup the world
Stop the server
Remove xycraft mod from the mods folder
Start the server
If it starts without the error then continue
- Stop the server
- Put Xycraft mod back
- Start the server

Be warned doing the above will remove every xycraft block from your world, tanks, liquid in tanks, fabricators, everything xycraft, hence backing up the world first.

Ok, I tried what you said and got this error after taking Xycraft out and attempting to start the server.

Download all the mods again for your server and replace the existing ones in the coremods and mods folder.

I know this is completely irrelevant to the topic, but i really need help I am playing minecraft on FTB ultimate + Optifine HD U D5, Reis minimap, Mouse Tweaks BETA 4, Armor StatusHUDv1.6, bspkrsCorev2.02, LiquidMetals-0.1.18, LogisticsPipes-0.7.0.96, MorePistonsv1.2.4, Pams HarvestCraft Base 1.1. The game loads up fine, but when i go to open my world, i get this, full log, but probably crash at end? (there is some red text towards the start of the log) Can somebody help? http://pastebin.com/GFvRBeca
I didnt even change any of the mods either, just the gregtech config slightly? and repatched the texture pack i'm using (soartex fanver + patched for added mods.)

Actually, dont worry, it was just the texture pack but if anyone could figure out how i could use it then i would be eternally grateful
