First of all, you should go get 64 bit Java.

For the problem, try redownloading the launcher.

I have 64-Bit Java, let me try it now, then get back to you.

EDIT: I ran it with allocating 3.75GB of RAM, and it still crashed....I'm going to try redownloading the FTB launcher.

EDIT #2: It still crashes....do you think downloading Java 7 along with Java 8 will do the trick?
