I am running a modpack server and after some hours the server crashed. Then i updated some mods and now there is only one errror and i dont know what to do. The modpack is my own.

Here is the pastebin link for the crashlog http://pastebin.com/vkZJUETK

• EnderIO: EnderIO-1.7.10-2.3.0.429_beta
• EnderCore: EnderCore-1.7.10-0.2.0.39_beta
• Minecraft: 1.7.10
• Forge: forge-1.7.10-10.13.4.1614-1.7.10-universal

Your world got damaged by the crash. Load your last backup from before it.

Where can i find the last backup? is it in the main server folder?
