all mod packs crash

[avid44]

for the past week i havent been able to play as it keeps cutting out.i get onto the launcher fine but as soon as i launch any mod pack the test screen that comes up becomes littered with red text. then the main screen says not responding and closes. i have re installed a few times, i have reinstalled java many times. i could post the red text if needed but there is alot on there
thanks

It will. Uninstall the 32bit Java and install the 64bit version instead.
