Modded Minecraft Crash (Yogcast Complete Pack)

Hello. I have recently had a problem in which whenever I join this server I would crash to desktop before seeing the world. I have never had this problem before on this server and have joined it multiple times in the past. I have tried reinstalling the modpack but it still happens.

I am also using Java 7
