Minecraft Crashes when loading a world

  • Hello all


    I Have recent installed Minecraft have added all the pre-install mods that are required for industrial craft2 (I also have Rei's Minimap installed)


    I have ran Minecraft after every single mod I installed (Minecraft would run fine)


    Then when I added the industrial craft 2 .jar file to the mods file Minecraft would freeze on the Mojang logo (I over came this by installing the sound fix)


    But now I have a new problem when I go to load a current or new world (Creative or Survival) Minecraft will go to the loading block screen then immediately switch to the saving block screen (which appears when you have run out of memory) then the screen goes black and after a minute or so Minecraft crashes


    After running Minecraft via command prompt (So it delivered A error message I came across this error message:
