Help me please! :(

[SweetSnowEcho]

I'm have problems with my hexxit lately aka starting yesterday. My game kept crashing after only a few minutes something about java and so today i try and get on and it crashes again and then when i try to go into one of my worlds the world won't even load, it gets stuck on the building terrain screen. so i updated my java and that didn't help and i'm at my wits end and don't know what to do. i've tried uninstalling and reinstalling the mod pack and that doesn't help i've tried restarting my computer, that doesn't help. I've tried uping the ammount of allowed java for the launcher that doesn't help and i...i just want to play my hexxit T_T so please someone help me.

 this is my problem but i posted it in another forum thread before i realized this bug one existied.
