Tekkit crashing problems need help!!

[mmmec]

I tried posting in questions and received no help but every time up loading any world, even a brand new one, in tekkit the game crashes. I get error messages and in the new worlds I am not even able to move break or place any blocks before it happens. I just get the world fully loaded then a white screen and have to relaunch. Ive tried reinstalling technic and tekkit, reinstalling java, and i never have anything else open when I launch so memory is not an issue (also checked to make sure) All other modpacks work fine. I am running Windows 8 64 bit if that helps at all.
