i have currently got a few mods on my pc with the main ones being buildcraft and equivalent exchange. i would like to add industrial craft to the mix but whenever i install it in whatever way my minecraft manages to crash and it wont let me access industrialcraft. i have watched several youtube videos on it and this has got me nowhere. i assumed recently it was because my mc forge was not up to the latest date, but this still didnt make a difference when i updated it. this is the error report below, i couldnt scroll down before the report disapeered so this is imcomplete.
