Problem [Direwolf20] Crash on startup "Exception in server tick loop"

[iAnDx]

Hi guys, i recently started a server with some friends to play the Direwolf20 mod pack.
As the title says, when i try to startup the server it crashes and gives me this log: http://pastebin.com/vJfig5wL
In the console i got this: http://pastebin.com/w7pSNkMD
Sorry for my bad english but it's not my native language.

Same. Please help. Make the burning stop.

Is it a clean install of the server or an update of an older server?
