Tekkitmain not working

Title: Tekkitmain not working

Version: 1_0_3

OS: Windows 8 v 6.2 64 bit

Java Version: Java 7 update 45 (64 bit) and underneath that there is java 7 update 51. my operating system is windows 8 64 bit.

Description of Problem:

I play on tekkit main, and shorty after making and placing a magma crucible, my game began severely lagging, then crashed. At this point all mods on the technic launcher are not working. Half the time they all show "offline status" and other times they appear normal and I run the modpack, but it freezes when "building terrain" pops up. I deleted the .technic file to see if re downloading it would fix, but a separate error occurs when I do that, saying that there was trouble downloading.
