Ive tried for months to play the Diamond Dimensions ModPack and all I ever get is this (Above)

• It looks like that pack has Optifine built into it. That may be causing your problems (and would require you replacing the modpack.jar with the Forge universal jar to remove it)
• You seem to be allocating a very small amount of RAM. Try bumping that up if you can.
• The mod pack is what I would call "poorly assembled". There is a ton of extraneous crap in the bin folder.
