Unexpected Error

[edbony]

Sorry people if I am in the wrong place for this, I didn't know where to ask.

Since this morning, I keep getting this (http://pastebin.com/ANMvBEGc) crash while joining my server. I increase both the server and my client's permgen and the ram, but nothing seems to work.

If someone would be kind enough to help me it would be greatly appreciated.

When I join I see the GUI with a purple background.

Also, I can provide my server files if needed.

I keep getting that error too. Are you near a Better Dungeons dungeon when that happens?
